  • Constraining a class of 𝐵��−𝐿�� extended models from vacuum stability and perturbativity 
    Mondal, Tanmoy (APS, 2014-03)
    The precise knowledge of the Standard Model (SM) Higgs boson and top-quark masses and couplings are crucial to understand the physics beyond it. An SM-like Higgs boson having a mass in the range of 123–127 GeV squeezes the ...
  • Class of Higgs-portal dark matter models in the light of gamma-ray excess from galactic center 
    Mondal, Tanmoy (Elsevier, 2015-05)
    Recently the study of anomalous gamma-ray emission in the regions surrounding the galactic center has drawn a lot of attention as it points out that the excess of gamma-ray in the low latitude is consistent with the emission ...
  • Copositive criteria and boundedness of the scalar potential 
    Mondal, Tanmoy (APS, 2014-05)
    To understand physics beyond the standard model it is important to have the precise knowledge of Higgs boson and top quark masses as well as strong coupling. A recently discovered new boson which is likely to be the standard ...
  • Constraining minimal 𝑈��⁢(1)𝐵��−𝐿�� model from dark matter observations 
    Mondal, Tanmoy (APS, 2014-03)
    We study the 𝐵−𝐿 gauge extension of the Standard Model which contains a singlet scalar and three right-handed neutrinos. The vacuum expectation value of the singlet scalar breaks the 𝑈⁢(1)𝐵−𝐿 symmetry. Here the ...
  • Searching for a light Higgs boson via the Yukawa process at lepton colliders 
    Mondal, Tanmoy (Elsevier, 2020-03)
    We explore the prospect of Yukawa production of a light boson which can exist in an extended Higgs sector. A particularly interesting case is the light pseudoscalar in Type-X two Higgs doublet model which can explain the ...
  • Models of decaying FIMP Dark Matter: potential links with the Neutrino Sector 
    Mondal, Tanmoy (2020-08)
    The absolute stability of a dark matter (DM) particle is not a binding requirement. Here we suggest a few scenarios where the DM particle is liable to decay via extremely feeble interactions. This can happen via inexplicably ...
  • Explaining g − 2 anomalies in two Higgs doublet model with vector-like leptons 
    Mondal, Tanmoy (Springer, 2020-11)
    We consider the two Higgs doublet model (2HDM) along with a generation of vector-like lepton doublet and singlet to explain the observed discrepancies in the electron and muon anomalous magnetic moments. The type-X ...
  • Leptophilic bosons and muon g-2 at lepton colliders 
    Mondal, Tanmoy (Springer, 2021-07)
    A light leptophilic boson (scalar or pseudoscalar) has been postulated to explain the muon g-2 anomaly and could be a portal to dark matter. Realizing the leptophilic nature of a singlet boson in the framework of the ...
  • Inverse seesaw and (g − 2) anomalies in B − L extended two Higgs doublet model 
    Mondal, Tanmoy (Elsevier, 2022-03)
    We propose a gauged extended two Higgs doublet model to explain both neutrino mass and lepton anomalous magnetic moments (). Neutrino mass is generated via an inverse seesaw mechanism by introducing singlet fermions. ...
  • Same sign trilepton as signature of charged Higgs in two Higgs doublet model 
    Mondal, Tanmoy (Springer, 2022-05)
    We explored the prospect of looking for a fermiophobic charged Higgs (H±) via the same sign trilepton signal at the LHC. A fermiophobic scenario appears in the type-I two Higgs doublet model where the coupling of the H± ...
  • Strings near black holes are Carrollian 
    Banerjee, Aritra (2024-03)
    We demonstrate that strings near the horizon of a Schwarzschild black hole, when viewed by a stationary observer at infinity, probe a string Carroll geometry, where the effective lightspeed is given by the distance from ...
  • Semiclassical strings in supergravity PFT 
    Banerjee, Aritra (Springer, 2014-10)
    Puff field theory (PFT) is an example of a non-local field theory which arises from a novel embedding of D-branes in a Melvin universe. We study several rotating and pulsating string solutions of the F-string equations of ...
  • Spiky strings on 𝐴��𝑑��𝑆��3×𝑆��3 with NS-NS flux 
    Banerjee, Aritra (APS, 2014-11)
    We study rigidly rotating strings in the background of 𝐴𝑑𝑆3×𝑆3 with Neveu-Schwarz fluxes. We find two interesting limiting cases corresponding to the known giant magnon and the new single spike solution of strings in ...
  • On the rotating and oscillating strings in (AdS3 × S3)k 
    Banerjee, Aritra (Springer, 2014-09)
    We study rigidly rotating strings in the ϰ-deformed AdS 3 × S 3 background. We find out two classes of solutions corresponding to the giant magnon and single spike solutions of the string rotating in two S 2 ϰ subspace of ...
  • Spiky strings in ϰ-deformed AdS 
    Banerjee, Aritra (Springer, 2015)
    We study rigidly rotating strings in ϰ-deformed AdS background. We probe this classically integrable background with ‘spiky’ strings and analyze the string profiles in the large charge limit systematically. We also discuss ...
  • A note on oscillating strings in AdS3×S3 with mixed three-form fluxes 
    Banerjee, Aritra (Springer, 2015)
    We present a detailed study of the pulsating string solutions in AdS3 × S 3 supported by both RR and NS-NS fluxes. This background has recently been proved to be integrable. We find the dispersion relation between the ...
  • Multi-spike strings in AdS3 with mixed three-form fluxes 
    Banerjee, Aritra (Springer, 2016-05)
    The string sigma model in AdS3 ×S 3 supported by mixed three-form fluxes has recently been proved to be integrable which led to a plethora of work in this background including proposals for S matrix and study of semiclassical ...
  • D1 string dynamics in curved backgrounds with fluxes 
    Banerjee, Aritra (Springer, 2016)
    We study various rotating and oscillating D-string configurations in some general backgrounds with fluxes. In particular, we look for solutions to the equations of motion of various rigidly rotating D-strings in AdS3 ...
  • On circular strings in (AdS3 ×S3)_k , Aritra Banerje 
    Banerjee, Aritra (Springer, 2016)
    The so called one-parameter (often called ϰ) deformed AdS string sigma models have attracted a lot of attention lately in the study of integrability in string theory. We construct various circular string solutions in the ...
  • Inhomogeneous Tensionless Superstrings 
    Banerjee, Aritra (Springer, 2018-02)
    We construct a novel tensionless limit of Superstring theory that realises the Inhomogeneous Super Galilean Conformal Algebra (SGCA I ) as the residual symmetry in the analogue of the conformal gauge, as opposed to previous ...
