A UV complete model where the Dark Matter particle interacts with gluons via a colored scalar mediator provides a viable phenomenological model that can be explored at Hadron colliders. Leading order contributions to mono-jet production which are loop-induced suffer from large-scale uncertainties. NLO QCD corrections are needed to bring down the scale uncertainties. Keeping this goal in mind, we c

We analyze new signals of a 3-Higgs Doublet Model (3HDM) at the Large Hadron Collider (LHC) where only one doublet acquires a Vacuum Expectation Value (VEV), preserving a parity Z2. The other two doublets are inert and do not develop a VEV, leading to a dark scalar sector controlled by Z2, with the lightest CP-even dark scalar H1 being the DM candidate. This leads to the loop-induced decay of the

FlexibleSUSY is a tool allowing to study phenomenology of user defined (both supersymmetric or not) BSM models. In a recent update we have extended it by adding the possibility to compute scalar decays. Building on that work, in this talk I will present an interface between FlexibleSUSY and HiggsTools - a library allowing to confront predictions for Higgs sectors with experimental data. As an appl

One simple way to lower the scale of the seesaw mechanism that generates neutrino masses is to attribute part of their smallness to a suppressed vacuum expectation value of a second Higgs doublet as in the neutrinophilic 2HDM or similar. On that structure we add one charged singlet scalar to induce a chirally enhanced contribution to (g − 2)μ with the same righthanded neutrinos of the seesaw. W

In this talk, we show that two WIMPs produced in the decay chains having sufficient mass splitting can yield a double peak in missing energy or missing transverse momentum distribution of multilepton/multijet signal. We argue that these peaks can be distinguished in terms of height and separation by some carefully crafted kinematic variables. For mono-X signal however, such double peak behavior ar

In composite Higgs models the Higgs boson is not an elementary particle, but of composite nature, emerging as a pseudo Nambu-Goldstone boson of a strongly interacting sector. In a composite 2-Higgs-Doublet Model (2HDM) a 2HDM-like structure is generated but with couplings already predetermined by the composite nature of the model. In this talk, we present Higgs pair production through gluon fusion

The investigation of the trilinear self-coupling of the discovered Higgs boson is one of the main goals of particle physics in the near future.
We provide predictions for this coupling, expressed in terms of the coupling modifier $\kappa_{\lambda}$, incorporating one-loop corrections within arbitrary renormalizable QFTs.
The presented framework allows to apply a wide class of pre- and user-defin

Existing studies of Higgs-tau Yukawa coupling allows for the presence of a non-zero CP-odd contribution. This is usually probed and constrained at the LHC by studying the distribution of events with respect to the angle between the two tau decay planes in H -> tau+ tau- decay. We study another interesting signature of CP violation, namely forward-backward asymmetry in the decay H -> tau+ tau- gamm

We study the anomalous ZZγ and Zγγ couplings that can be probed via
Zγ production at the e^+ e^− colliders. We take Standard Model Effective Field Theory (SMEFT) approach to examine these anomalous neutral triple gauge couplings in a model-independent way. There are four independent dimension-8 operators that generate these gauge interactions, one of them is CP-conserving and rest three are
