I will talk about Higgs (New) physics measurements at the LHC, where we stand in precision measurement, and how are we improving with near future data.
Many standard model extensions predict vector-like fermionic top-partners at the TeV scale. The searches by ATLAS and CMS typically focus on VLQ decays into a 3rd generation quark and an electroweak boson (W, Z, h). If BSM particles lighter than the top partner exist, they can give rise to exotic top partner decay channels. We consider several scenarios, identify signatures which are currently...
We have studied the constrained minimal supersymmetric standard model with three right-handed neutrinos, and investigated whether there still is a parameter region consistent with all experimental data/limits such as the baryon asymmetry of the Universe, the dark matter abundance and the lithium primordial abundance. Using Casas-Ibarra parametrization, we have found a very narrow parameter...
We perform a multivariate analysis of the Higgs-pair production in $HH \to b\bar b \gamma\gamma$ channel at the HL-LHC to probe the trilinear Higgs self-coupling $\lambda_{3H}$, which takes the value of 1 in the SM. We consider all the known background processes. And, for the signal, we adopt the most recent event generator of OWHEG-BOX-V2 to exploit the NLO distributions for Toolkit for...
In this talk, I will discuss the production of the Standard Model (SM) Higgs Boson and its subsequent decays into hadrons (e.g. b-quarks) at the LHC and future colliders. The SM Higgs Boson, due to its long lifetime compared to electroweak gauge bosons and the top quarks, decays outside the Quark-Gluon Plasma (QGP). Therefore, its hadronic decays may experience little or no screening from the...
