Good Phenomenology in Hard Time: A pragmatic approach



Event Code: 2025032102264
Speaker: Dr. Agnivo Sarkar (NPDF fellow, Harish-Chandra Research Institute)

After the discovery of the Higgs boson, both the ATLAS and the CMS collaborations have been conducting several analyses to scrutinise its properties. In fact, one of the primary goals of future HL-LHC is to reveal precise information regarding this newly discovered scalar. Parallaly, hunting for new physics signals, which is in general dubbed as "Direct searches at collider", remains one of the major motivations for the particle physicists to embark on the BSM journey. In this talk, we will systematically formulate a methodology to establish that both these programs can be complementary to each other. To do so, we will consider the following question as a test problem.

Is there a relative minus sign between two cubic couplings g^{WW}_{h_{125}} and g^{ZZ}_{h_{125}}?

The major finding of this talk is to realise how direct search brings forth additional information regarding the 125 GeV Higgs boson properties as well as the mechanism of the electroweak symmetry breaking.

All are cordially invited.
