Implications of dark sector mixing on leptophilic scalar dark matter
Sreemanti Chakraborti, Rashidul Islam
We propose a new viable outlook to the mixing between a singlet and a doublet leptonic dark sector fields. This choice relaxes the dark matter (DM) search constraints on the quinte…
Multilepton signatures for scalar dark matter searches in coannihilation scenario
Sreemanti Chakraborti, Rashidul Islam
We revisit the scalar singlet dark matter (DM) scenario with a pair of dark lepton partners which form a vectorlike Dirac fermionic doublet. The extra doublet couples with the Stan…
Dark matter in the Randall-Sundrum model
Mukesh Kumar, Ashok Goyal, Rashidul Islam
In Ref. \cite{Goyal:2019vsw}, we had considered simplified dark matter models interacting gravitationally with the Standard Model particles in a Randall-Sundrum frame work where mo…
Dark matter in the Randall-Sundrum model with non-universal coupling
Ashok Goyal, Rashidul Islam, Mukesh Kumar
We consider simplified dark matter models (DM) interacting gravitationally with the standard model (SM) particles in a Randall-Sundrum (RS) framework. In this framework, the DM par…
Fingerprinting the Top quark FCNC via anomalous couplings at the LHeC
Subhasish Behera, Rashidul Islam, Mukesh Kumar +2
A study of the top quark \emph{Flavour Changing Neutral Current} (FCNC) through -boson has been performed in the proposed future collider for the energy, $E_{e(p)} = 60~(…
Probing Multicomponent Extension of Inert Doublet Model with a Vector Dark Matter
Sreemanti Chakraborti, Amit Dutta Banik, Rashidul Islam
Although theoretically well-motivated as a minimal consistent Dark Matter (DM) model, the Inert Doublet Model (IDM) fell short in explaining the existence of DM in the intermediate…
Scattering unitarity with effective dimension-6 operators
Swagata Ghosh, Rashidul Islam, Anirban Kundu
The effects of physics beyond the Standard Model may be parametrized by a set of higher-dimensional operators leading to an effective theory. The introduction of these operators ma…
Differential cross section for the Higgs boson production in 4-lepton channel and -factorization
Vaibhav S. Rawoot, Rashidul Islam, Mukesh Kumar
We present our study of the differential cross section for the Higgs boson production in -factorization framework. The -factorization formalism includes a convolution ove…
Probing anomalous couplings using di-Higgs production in electron-proton collisions
Mukesh Kumar, Xifeng Ruan, Rashidul Islam +4
A proposed high energy Future Circular Hadron-Electron Collider would provide sufficient energy in a clean environment to probe di-Higgs production. Using this channel we show that…
Investigating Unitarity in Presence of Anomalous Couplings
Mamta Dahiya, Sukanta Dutta, Rashidul Islam
We perform a model independent analysis of the helicity amplitudes at high energy for all the scattering processes involving gauge and Higgs bosons in the presence of anoma…
Anomalous Higgs Couplings as a Window to New Physics
Debajyoti Choudhury, Rashidul Islam, Anirban Kundu
The initial data on the production and decay of the Higgs boson reported significant deviations from the Standard Model (SM) expectations, prompting much speculation about its coup…
Constraining Unparticles from Top Physics at TeVatron
Mamta Dahiya, Sukanta Dutta, Rashidul Islam
We study and analyze the recent observations of the top pair production at TeVatron through flavor conserving and flavor violating channels vec…
