The LPC hosted its 12th annual school, the second to be held fully virtually, from Jan. 4-14, 2022. More than 120 students, postdocs and faculty from around the world participated.

The Fermilab Scientist Advisory Council has recently welcomed new members and elected new co-chairs Bo Jayatilaka and Brendan Kiburg. The SAC meets regularly with the Directorate and discusses topics of interest in both short- and long-term plans for the laboratory’s research program as well as issues related to careers and professional development of the scientific staff.
It’s worth considering why organizations such as Fermilab are increasingly turning their attention to diversity and inclusion and what they mean to the wider global community of high-energy physics.
What do high-energy scientists mean when they talk about a trigger? How does it work? And how impressive are the CMS triggers? (They’re pretty impressive.)
The Standard Model allows for the Higgs boson to decay to identically flavored pairs of leptons, such as electrons and muons, but not to mixed pairings of lepton flavors. Evidence of the latter would be a sign of new physics.
A bump in the CMS data at 750 GeV hints at the possibility of a new particle.
CMS looks for evidence of J/ψ mesons in near-collision events in the LHC’s 2011 heavy-ion run, during which lead nuclei were accelerated to an unprecedented energy of 574 trillion electronvolts.
Protons that just miss each other as they approach generate photons that have enough energy to produce pairs W bosons, massive particles — and without any of the additional activity that is seen in messier head-on proton collision events.
Much the way football analysts evaluate quarterbacks using a numerical quarterback rating, particle physicists have measured statistics to evaluate whether particle physics events result from known Standard Model processes or something else, such as supersymmetry.
CMS scientists recently looked for heavy neutrinos, which could lead to evidence for “seesaw mechanism” theories that propose why the neutrinos we know about are the masses that they are.
