More like this Whats the story on the actual progress of trying to put it within the standard model? For as long as I remember, the story (here on blog, but elsewhere as well) revolves around more and more observations that its real. OK, but what about the actual particle? Are we really out of ideas for more than 20 years? IMO axions sound promising, but is there no model that doesnt require super simetry? It almost.. almost.. seems like the majority of community has accepted it, and fell into ...

“There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.” -Lord Kelvin The particle physics ‘nightmare scenario’ was that the LHC at CERN would achieve its desired energies and collision rates, that it would find a single Higgs boson between about 120 and 140 GeV, and that it would see absolutely nothing else. No new particles, no bizarre decays, nothing that couldn’t be accounted for by the Standard Model. With the latest release, t...

This book examines the notions of waves, particles and forces and gives a complete conceptual explanation of Quantum Field Theory and the Standard Model of particle physics. It addresses all readers seeking a deep understanding of the theory without delving into the detailed mathematics.

Partner in Nobel Prize-winning Discovery of Muon Neutrino at Brookhavens Alternating Gradient Synchrotron DOE/Brookhaven National Laboratory Jack Steinberger, who with Leon Lederman and Melvin Schwartz was awarded the 1988 Nobel Prize in physics for their 1962 discovery of the muon neutrino, died on Saturday, December 12, 2020, at his home in Geneva. He was 99. "Jack Steinberger was a remarkable man who played a key role in one of the most impactful discoveries in particle physics of the 20th c...

Physicists from the CMS (Compact Muon Solenoid) Collaboration at CERN’s Large Hadron Collider (LHC) report the results of a new search for leptoquarks produced singly and in pairs in proton-proton collisions. A collision event recorded by CMS at the start of the data-taking run of 2018. CMS sifts through such collisions up to 40 million times per second looking for signs of leptoquarks.

Credit: GBO / AUI / NSF In the 1970s, physicists uncovered a problem with the Standard Model of particle physics—the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong interactions; the fourth is gravity). They found that, while the theory predicts that a symmetry between particles and forces in our Universe and a mirror version should be broken, the experiments say otherwise. This mismatch between theory and observations is dubbed “the S...

(Image: CERN) Jack Steinberger, a giant of the field who contributed so much to the experimental development of the Standard Model, passed away on 12 December 2020 aged 99. Born in the Bavarian town of Bad Kissingen in 1921, he left Germany at the age of 13 to escape rising antisemitism and settled in the United States. After receiving a degree in chemistry from the University of Chicago, he turned his attention to physics, working at the MIT radiation laboratory through the war year...

Our sixth story in the LHC Physics at Ten series looks at the precision measurements of the Standard Model made at the Large Hadron Collider Bs0→ μ+μ- decay candidate event recorded in 2016 (Image: CERN) At the start of 2010, the particle physics community was abuzz with hopes and excitement. Just a few weeks later, the experiments at the Large Hadron Collider (LHC) would venture beyond the energy frontier, where physicists hoped to find exotic particles that would pav...

The CMS detector (Image: CERN) At the most fundamental level, matter is made up of two types of particles: leptons, such as the electron, and quarks, which combine to form protons, neutrons and other composite particles. Under the Standard Model of particle physics, both leptons and quarks fall into three generations of increasing mass. Otherwise, the two kinds of particles are distinct. But some theories that extend the Standard Model predict the existence of new particles...

Jack Steinberger, Nobel Winner in Physics, Dies at 99 Dr. Steinberger shared the prize in 1988 for expanding understanding of the neutrino, a staggeringly ubiquitous subatomic particle.
