We propose a novel kinematic method to expedite the discovery of the double Higgs ($hh$) production in the $ell^+ell^- b bar{b} + E_T hspace{-0.52cm} big / ~$ final state. We make full use of recently developed kinematic variables, as well as the variables $it Topness$ for the dominant background (top quark pair production) and $it Higgsness$ for the signal. We obtain a significant increase in sensitivity compared to the previous analyses which used sophisticated algorithms like boosted decision trees or neutral networks. The method can be easily generalized to resonant $hh$ production as well as other non-resonant channels.
At a high energy $ep$ collider, such as the Large Hadron-Electron Collider (LHeC) which is being planned at CERN, one can access the $WWgamma$ vertex exclusively in charged current events with a radiated photon, with no interference from the $WWZ$ ve
For the foreseeable future, the exploration of the high-energy frontier will be the domain of the Large Hadron Collider (LHC). Of particular significance will be its high-luminosity upgrade (HL-LHC), which will operate until the mid-2030s. In this en
A radion in a scenario with a warped extra dimension can be lighter than the Higgs boson, even if the Kaluza-Klein excitation modes of the graviton turn out to be in the multi-TeV region. The discovery of such a light radion would be gateway to new p
We investigate the anomalous flavour changing neutral current (FCNC) interactions of top quark through the process $e^{-}pto e^{-}W^{pm}q+X$. We calculate the signal and background cross sections in electron proton collisions at Large Hadron electron
We investigate Higgs boson pair production at hadron colliders for Higgs boson masses m_Hleq 140 GeV and rare decay of one of the two Higgs bosons. While in the Standard Model the number of events is quite low at the LHC, a first, albeit not very pre
