American theoretical physicist Joseph Polchinski once said the existence of magnetic monopoles is ‘one of the safest bets that one can make about physics...
The Forward Search Experiment (FASER) at CERN’s Large Hadron Collider (LHC) is designed to search for extremely weakly interacting particles. Such particles...
Physicists with the CMS Collaboration at CERN’s Large Hadron Collider (LHC) have successfully measured the effective leptonic electroweak mixing angle....
According to physicists from the CMS Collaboration at CERN’s Large Hadron Collider (LHC), it is the first time that this process has been seen in proton-proton...
The formation of galaxies by gradual hierarchical co-assembly of baryons and cold dark matter halos is a fundamental paradigm underpinning modern astrophysics...
Physicists with the CMS Collaboration at CERN’s Large Hadron Collider (LHC) have presented their first search for new physics using data from LHC Run...
The key to understanding the mystery of elusive dark matter could lie with the dark photon, a hypothetical dark sector particle proposed as a force carrier...
Physicists report a new measurement of the muon magnetic anomaly using data collected in 2019 and 2020 by the Muon g-2 experiment at Fermilab National...
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...
