In the eleven years since its discovery, studies of the Higgs boson have become a central avenue for shedding light on the fundamental structure of the...
The first generation of stars in the Universe is yet to be observed. There are two leading theories for those objects: hydrogen burning Population III...
Physicists from the ATLAS and CMS collaborations at CERN’s Large Hadron Collider (LHC) have independently conducted extensive searches for the rare Higgs...
Symmetry is a tidy and attractive idea that falls apart in our untidy Universe. Indeed, since the 1960s, some kind of broken symmetry has been required...
Using the ForwArd Search ExpeRiment (FASER), a particle detector installed at CERN, particle physicists were able to detect very high energy neutrinos...
Physicists from the LHCb Collaboration at CERN’s Large Hadron Collider (LHC) have performed new tests of lepton universality, one of the basic principles...
Physicists from the ATLAS Collaboration at CERN’s Large Hadron Collider (LHC) have performed new measurements of Higgs boson’s decay width, which is...
Dark photons are hypothetical particles that could account for observations that cannot be explained by the Standard Model of particle physics.
Dark photons...
On July 4, 2012, physicists from the ATLAS and CMS collaborations at CERN’s Large Hadron Collider announced the observation of a Higgs boson at a mass...
To measure the lifetime of a free neutron, physicists take two approaches that should arrive at the same answer: one traps neutrons in a magnetic bottle...
Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge-parity asymmetry, which is required to explain...
Physicists from the CMS (Compact Muon Solenoid) Collaboration at CERN’s Large Hadron Collider (LHC) have substantially improved the precision with which...
Physicists from the Collider Detector at Fermilab (CDF) Collaboration have determined the mass of the W boson, a mediator of the weak force between elementary...
Dr. Raffaele Tito D’Agnolo from the French Alternative Energies and Atomic Energy Commission and Dr. Daniele Teresi from CERN have proposed a novel theory...
The Standard Model of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance...
The Higgs boson is peculiar in many respects. Like most other elementary particles, it is unstable and lives only for an extremely short time, 1.6*10-22...
Physicists from CERN’s LHCb (Large Hadron Collider beauty) Collaboration have carried out new tests of lepton universality, one of the basic principles...
Physicists from the ATLAS Collaboration at CERN’s Large Hadron Collider (LHC) have successfully performed measurements of ‘lepton flavor universality,’...
Physicists from the LHCb Collaboration at CERN have proved that a subatomic particle called the charm meson can switch into its antiparticle and back again....
Neutral pions (π0) have a lifetime of around 80 attoseconds, decaying into two photons. In new research, an international team of physicists has measured...
