Out of the loop: CMS advances in the search for a rare Higgs boson decay
Out of the loop: CMS advances in the search for a rare Higgs boson decay Completing the Higgs boson’s profile requires probing some of its rarest decay modes. Among the few still awaiting observation is the decay into a Z boson and a photon (H → Zγ), which occurs in only about one out of

Higgs boson and the quest for new physics
Higgs boson and the quest for new physics The discovery of a new particle in 2012 by the ATLAS and CMS experiments at CERN was just the beginning in understanding the properties of this particle and its potential link to some of the most pressing fundamental questions in modern physics. Following its discovery, the LHC

CERN experiments find first evidence for rare Higgs boson decay
CERN experiments find first evidence for rare Higgs boson decay The strength of the interaction between the Higgs field and a particle determines the mass it obtains from the Higgs and it is a mystery why the interaction strength is different for different particles. This puzzle is exacerbated as the leptons, quarks and neutrinos appear

The Higgs boson as a probe for new physics
The Higgs boson as a probe for new physics The discovery of the Higgs boson has ushered in a new era of exploration at the Large Hadron Collider (LHC). Persistent tensions in the Standard Model (SM) of particle physics compel us to seek out physics beyond the SM (BSM) at the TeV scale, and the

Higgs boson observed decaying to bottom quarks
Higgs boson observed decaying to bottom quarks Last month, the ATLAS and CMS collaborations jointly announced the discovery of the Higgs boson decaying into a matter-antimatter pair of bottom quarks. Previously, the Higgs boson has been observed decaying to photons, tau-leptons, and W and Z bosons. However, these impressive achievements represent only 30 percent of

ATLAS observes Higgs boson produced in association with top quarks
ATLAS observes Higgs boson produced in association with top quarks The ATLAS collaboration presented the first evidence of “ttH production”, a rare process where a pair of top quarks emits a Higgs boson. Observing this process would provide new insight into the Higgs mechanism and allow for new studies of how unknown physics might (or

007 reasons for physics beyond the Standard Model
007 reasons for physics beyond the Standard Model The 5th of July marks the fifth anniversary since the discovery of a Higgs boson at the LHC. Summarizing notes for a recent set of lectures at the Asia-Europe-Pacific School of High-Energy Physics, John Ellis reviews events leading to the discovery of the Higgs boson and what

Physics at 100 TeV
Physics at 100 TeV A report discussing the opportunities for physics discoveries with a future 100 TeV hadron circular collider was presented earlier this summer during the 2016 FCC Week. A future hadron-hadron collider machine will be able to cover previously unexplored territory at energies never before reached in a laboratory environment. Standard Model calculations
