CP violation or new physics?
(Phys.org)—Over the past few years, multiple neutrino experiments have detected hints for leptonic charge parity (CP) violation—a finding that could help explain why the universe is made of matter and not antimatter. ...

Evidence suggests subatomic particles could defy the standard model
The Standard Model of particle physics, which explains most of the known behaviors and interactions of fundamental subatomic particles, has held up remarkably well over several decades. This far-reaching theory does have ...

Hunt for the platypus particle
All of the atoms in our bodies are made of electrons, protons and neutrons, and the protons and neutrons can be further broken down into quarks. Fundamentally, then, we are made of only two types of particles: electrons and ...

BaBar experiment data hint at cracks in the Standard Model
(Phys.org) -- Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe works on subatomic scales. The data from BaBar, ...

Will the real Higgs Boson please stand up?
Although physicists from two experiments at CERN's Large Hadron Collider and from Fermilab’s Tevatron collider recently reported at the Europhysics Conference on High Energy Physics that they didn't find the Higgs boson, ...

CDF and D0 joint paper puts a further squeeze on the Higgs
Almost a decade after the experiments at CERN’s Large Electron-Positron (LEP) collider set a limit on the mass of the Higgs boson of 114.4 GeV/c2, the two experiments at Fermilab’s Tevatron, CDF and D0 have been able ...
