HEP@VUB meetings

Jean Sacton seminar room (1G003) (Universe)

External Speaker: Filippo Sala (DESY)

12:00 → 13:00 Proposal of new LHC searches for low-mass resonances

Several motivated extensions of the Standard Model feature new scalar bosons below the Higgs mass. A primary example is constituted by pseudo-Goldstone bosons (often referred to as axion-like particles) from an approximate global symmetry. In this talk I will i) review the models that predict these particles to be within experimental reach, and ii) discuss some most promising ways to look for them at colliders. I will present recent advances both on i), discussing the supersymmetric R-axion, and on ii), presenting a new LHC bound on diphoton resonances down to 10 GeV of mass, and proposing new searches along these lines.
