The ‘nuclear pasta’ in neutron stars could transform particle physics
To learn more about the mysteries of quantum chromodynamics, we are probing the universe’s densest stars, says Chanda Prescod-Weinstein in her latest column Source: https://www.newscientist.com/article/mg24432540-100-the-nuclear-pasta-in-neutron-stars-could-transform-particle-physics/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
ATLAS Experiment releases new search for strong supersymmetry
New particles sensitive to the strong interaction might be produced in abundance in the proton-proton collisions generated by the Large Hadron Collider (LHC) – provided that they aren’t too heavy. These particles could be the partners of gluons and quarks predicted by supersymmetry (SUSY), a proposed extension of the Standard Model of particle physics that would expand its predictive power to…
New milestone reached in the study of electroweak symmetry breaking
In the Standard Model of particle physics, elementary particles acquire their masses by interacting with the Higgs field. This process is governed by a delicate mechanism: electroweak symmetry breaking (EWSB). Although EWSB was first proposed in 1964, it remains among the least understood phenomena of the Standard Model as a large dataset of high-energy particle collisions is required to probe it….
ATLAS Experiment finds evidence of charge asymmetry in top-quark pairs
Among the most intriguing particles studied by the ATLAS Experiment is the top quark. As the heaviest known fundamental particle, it plays a unique role in the Standard Model of particle physics, and perhaps in physics beyond the Standard Model. …
Exotic Particles Called Pentaquarks May Be Less Weird Than Previously Thought
sciencehabit writes from a report via Science Magazine: Four years ago, when experimenters spotted pentaquarks — exotic, short-lived particles made of five quarks — some physicists thought they had glimpsed the strong nuclear force, which binds the atomic nucleus, engaging in a bizarre new trick. New observations have now expanded the zoo of pentaquarks, but suggest a tamer explanation for their…
Physicists Search for Monstrous Higgs Particle. It Could Seal the Fate of the Universe.

Quantum cloud computing with self-check
With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result…
