Hypothetical new particle could solve two major problems in particle physics

Posted by in category: particle physics

(Phys.org)—Although the Large Hadron Collider’s enormous 13 TeV energy is more than sufficient to detect many particles that theorists have predicted to exist, no new particles have been discovered since the Higgs boson in 2012. While the absence of new particles is informative in itself, many physicists are still yearning for some hint of “new physics,” or physics beyond the standard model.

In a new paper published in Physical Review Letters, physicists Yu-Sheng Liu, David McKeen, and Gerald A. Miller at the University of Washington in Seattle have hypothesized the existence of a that looks very enticing because it could simultaneously solve two important problems: the puzzle and a discrepancy in muon measurements that differ significantly from predictions.

“The new particle can account for two seemingly unrelated problems,” Miller told Phys.org. “We also point out several experiments that can further test our hypothesis.”

Scientists study effects of extra space dimensions in particle physics and cosmology

Posted by in categories: cosmology, particle physics

There are many theoretical models to explain such aspects of high energy physics as dark matter, theory of inflation, bariosynthesis, the Higgs mechanism, etc. The discovery of universal expansion is accelerating, precise measurements of characteristics of the cosmic microwave background, and indirect confirmations of the existence of dark matter have significantly advanced observational and theoretical cosmology. The connection between cosmological processes in the early universe and physics of elementary particles is getting clearer. Theories with additional compact measurements (multidimensional gravity) have contributed to the explanation of a series of phenomena in cosmology and the physics of elementary particles including inflation, baryon asymmetry, black holes and dark matter. Multidimensional gravity may become one of the basics of fundamental theoretical physics.

The development of colliders led to the discovery of a number of new particles, which was a great confirmation of the Standard Model ℠ of particle physics. The real SM triumph was the discovery of the Higgs boson in LHC experiments in CERN. However, despite the success of SM in , there is a series of questions and problems that can’t be explained by it—for example, baryon asymmetry, the origin of the Higgs field, the production of the early quasars, etc.

A theoretical direction, which is based on the idea of multidimensional gravity, is being developed at the MEPhI Department № 40 under the supervision of Professor S.G. Rubin. For the past several years, interesting results have been obtained on the basis of this research. In a thesis by Alexey Grobov titled “Effects of extra spaces in particle physics and cosmology,” multidimensional gravitational models contribute to better understanding of connections between astrophysics and microphysics phenomena.

Nano-lipid Particles From Edible Ginger Could Improve Drug Delivery for Colon Cancer, Study Finds

Posted by in categories: biotech/medical, food, nanotechnology, particle physics

A new tool to battle colon cancer.


Edible ginger-derived nano-lipids created from a specific population of ginger nanoparticles show promise for effectively targeting and delivering chemotherapeutic drugs used to treat colon cancer, according to a study by researchers at the Institute for Biomedical Sciences at Georgia State University, the Atlanta Veterans Affairs Medical Center and Wenzhou Medical University and Southwest University in China.

Colorectal cancer is the third most common cancer among men and women in the United States, and the second-leading cause of cancer-related deaths among men and women worldwide. The incidence of colorectal cancer has increased over the last few years, with about one million new cases diagnosed annually. Non-targeted chemotherapy is the most common therapeutic strategy available for colon cancer patients, but this treatment method is unable to distinguish between cancerous and healthy cells, leading to poor therapeutic effects on tumor cells and severe toxic side effects on healthy cells. Enabling chemotherapeutic drugs to target cancer cells would be a major development in the treatment of colon cancer.

New CERN LHC Experiments –“Predict a Boson Beyond the Higgs That Could Unlock Clues to Existence of Dark Matter”

Posted by in categories: cosmology, particle physics

Two separate experiments at the Large Hadron Collider at the European Organisation for Nuclear Research, on the French-Swiss border, appear to confirm the existence of a subatomic particle, the Madala boson, that for the first time could shed light on one of the great mysteries of the universe — dark matter.

For first time, carbon nanotube transistors outperform silicon

Posted by in categories: bioengineering, computing, nanotechnology, particle physics

For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power — resulting in longer battery life, faster wireless communication and faster processing speeds for devices like smartphones and laptops.

But a number of challenges have impeded the development of high-performance transistors made of carbon nanotubes, tiny cylinders made of carbon just one atom thick. Consequently, their performance has lagged far behind semiconductors such as silicon and gallium arsenide used in computer chips and personal electronics.

Colors from darkness: Researchers develop alternative approach to quantum computing

Posted by in categories: computing, particle physics, quantum physics

Another approach to QC; the title of the article is misleading because you still are using quantum properties in the approach.


Researchers at Aalto University have demonstrated the suitability of microwave signals in the coding of information for quantum computing. Previous development of the field has been focusing on optical systems. Researchers used a microwave resonator based on extremely sensitive measurement devices known as superconductive quantum interference devices (SQUIDs). In their studies, the resonator was cooled down and kept near absolute zero, where any thermal motion freezes. This state corresponds to perfect darkness where no photon — a real particle of electromagnetic radiation such as visible light or microwaves — is present.

However, in this state (called quantum vacuum) there exist fluctuations that bring photons in and out of existence for a very short time. The researchers have now managed to convert these fluctuations into real photons of microwave radiation with different frequencies, showing that, in a sense, darkness is more than just absence of light.

In a very high magnetic field a ‘massless’ electron can acquire a mass

Posted by in category: particle physics

An international team of researchers have for the first time, discovered that in a very high magnetic field an electron with no mass can acquire a mass. Understanding why elementary particles e.g. electrons, photons, neutrinos have a mass is a fundamental question in Physics and an area of intense debate. This discovery by Prof Stefano Sanvito, Trinity College Dublin and collaborators in Shanghai was published in the prestigious journal Nature Communications this month.

Physicist finds entanglement instantly gives rise to a wormhole

Posted by in categories: particle physics, quantum physics

Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics — so strange, in fact, that Albert Einstein famously referred to it as “spooky action at a distance.”

Essentially, entanglement involves two particles, each occupying multiple states at once — a condition referred to as superposition. For example, both particles may simultaneously spin clockwise and counterclockwise. But neither has a definite state until one is measured, causing the other particle to instantly assume a corresponding state.

The resulting correlations between the particles are preserved, even if they reside on opposite ends of the universe.

Liquid Metals to “Soft-Wire” Elastic Electronics

Posted by in categories: bioengineering, biological, particle physics, robotics/AI

“Liquid Metals to “Soft-Wire” Elastic Electronics”

A few years ago, some friends shared with me an amazing experiment of theirs involving liquid/ fluid base circuitry. Definitely is amazing; and is going to be amazing in where we are taking this type of technology along with synthetic biology.


The shape-shifting metals behind the T-1000 android assassin in the sci-fi movie Terminator 2 may not remain science fiction for long with the development of self-propelling liquid metals that could lead to the replacement of solid state circuits by elastic electronics.

Research pair create two-atom molecules that are more than a thousand times bigger than typical diatomic molecules

Posted by in categories: computing, particle physics, quantum physics

Perfecting the macro-molecule.


(Phys.org)—A pair of physicists with the Swiss Federal Institute of Technology in Switzerland has found a way to create very large diatomic molecules, and in so doing, have proved some of the theories about such molecules to be correct. In their paper published in Physical Review Letters, Johannes Deiglmayr and Heiner Saßmannshausen describe their experiments and results and why they believe such molecules may have a future in quantum computing.

Physicists have been interested in the properties of macromolecules for many years because they believe studying them will illuminate the fundamental properties of in general. Prior research has shown that large, two-atom molecules should be possible if they were put into a Rydberg state—in which the outer electron exists in a high quantum state, allowing it to orbit farther than normal from the nucleus—and thus allowing for the creation of molecules thousands of times larger than conventional diatomic molecules such as H2.
