Archyde Geneva – Physicists at the ATLAS experiment at the Large Hadron Collider (LHC) have achieved a significant milestone in the hunt for supersymmetry (SUSY), surpassing previous limitations set by the… You can read the full story here: ATLAS Excludes Supersymmetric Higgsinos with New LHC Results.

ATLAS sets new limits on the masses of supersymmetric higgsinos, surpassing results set by the Large Electron–Positron (LEP) collider experiments over 20 years ago. Supersymmetry (SUSY) is a compelling theory that predicts every Standard Model particle has a “super-partner.” Among these are higgsinos, the supersymmetric partners of the Higgs boson. If they exist, higgsinos could … Read more

One of the biggest open questions in particle physics today is how the Higgs boson interacts with itself. This “self-coupling” plays a pivotal role in determining the shape of the energy potential of the Higgs field, influencing both the early Universe evolution and the mechanism that gives mass to elementary particles. Physicists at the ATLAS … Read more

The onset of high-energy operation of the Large Hadron Collider (LHC) at CERN in 2010 heralded a new and transformative era in physics research. A powerful and versatile hadron collider paired with sophisticated particle detectors and worldwide grid computing, all performing beyond expectations, allowed the LHC experiments to chart new frontiers and advance particle physics. … Read more

Despite its wide-ranging success, the Standard Model leaves some of the universe’s deepest mysteries unanswered. What is dark matter? Why does matter dominate over antimatter? Given how no beyond-the-Standard-Model phenomena have yet been observed at the Large Hadron Collider (LHC), a question naturally arises: are physicists searching in the right place? Figure 1: The expected … Read more
