Scientists take the first step towards extending the Standard Model in physics

Researchers of Peter the Great St. Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from the Physikalisch Technische Bundesanstalt (PTB) and a number of German scientific organizations, calculated previously unexplored effects in atoms. The results were published in the Physical Review A, highlighted as an Editor’s Choice article. …

LHCb explores the beauty of lepton universality

The LHCb collaboration has reported an intriguing new result in its quest to test a key principle of the Standard Model called lepton universality. Although not statistically significant, the finding—a possible difference in the behavior of different types of lepton particles—chimes with other previous results. If confirmed, as more data are collected and analyzed, the results would signal a crack in…

Strange particles found in Antarctica cannot be explained by physics

A NASA science balloon picked up two high-energy particles and a new analysis reveals they cannot be explained by the standard model of particle physics Source: https://www.newscientist.com/article/2229988-strange-particles-found-in-antarctica-cannot-be-explained-by-physics/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

New Boson Appears In Nuclear Decay, Breaks Standard Model

An anonymous reader shares an excerpt from an Ars Technica article: In November, people started polishing a Nobel prize for a group of physicists who seemed to have found new boson. […] This result has been cooking for quite some time. The first experimental results date back to 2015, with publication in 2016. Essentially, the scientists took some lithium and shot…

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…

How Netflix Is Using Its Muscle To Push Filmmaking Technology Boundaries

Carolyn Giardina from The Hollywood Reporter writes about the growing influence Netflix has from hardware and software development to industry display standards. For example, as recently as six months ago, Netflix forbid Hollywood cinematographers from using a highly-popular camera because the standard model employed a 3.2K resolution sensor instead of a 4K sensor required for the streamer’s original programming. Netflix also…

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….
