|Title:||Hunt for low mass diphoton resonance at LHC and Kaon factory|
|Date (JST):||Wed, Jul 11, 2018, 13:30 - 14:30|
I discuss new strategies to hunt for a resonance in diphoton final state. First, I present a new bound on diphoton resonances using inclusive diphoton cross section measurements at the LHC (ATLAS and CMS), in the so-far poorly constrained mass range between the Upsilon and Z boson mass. This bound sets the current best limit on axion-like particles that couple to gluons and photons, for masses between 10 and 65 GeV. Also, I present an analysis for boosted diphoton resonance with a new photon isolation algorithm in the same mass region for the future LHC.
In the second part of the talk, I explore a possibility of O(10-100) MeV diphoton resonance hunt at Kaon factories, in particular utilizing J-PARC KOTO experiment.
