  • 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 ...
  • Fast spinning strings on η deformed AdS5 × S5 
    Banerjee, Aritra (Springer, 2018-02)
    In this paper, considering the correspondence between spin chains and string sigma models, we explore the rotating string solutions over η deformed AdS5 × S5 in the so-called fast spinning limit. In our analysis, we focus ...
  • Probing analytical and numerical integrability: the curious case of (AdS5 × S5)η 
    Banerjee, Aritra (Springer, 2018)
    Motivated by recent studies related to integrability of string motion in various backgrounds via analytical and numerical procedures, we discuss these procedures for a well known integrable string background (AdS5 × S5)η. ...
  • On multi-spin classical strings with NS-NS flux 
    Banerjee, Aritra (Springer, 2018)
    We study multi spin semiclassical strings in AdS3 × S3 × T4 background supported by a mixture of Neveu-Schwarz-Neveu-Schwarz (NS-NS) and Ramond-Ramond (R-R) fluxes. This ‘mixed flux’ background has been recently proved to ...
  • Exotic origins of tensionless superstrings 
    Banerjee, Aritra (Elsevier, 2020-02)
    A new type of tensionless superstring theory, called the Inhomogeneous tensionless superstring, has been recently introduced. This is characterised by a residual symmetry algebra on the worldsheet richer in structure than ...
  • On interpolating anomalous dimension of twist-two operators with general spins 
    Banerjee, Aritra (Springer, 2019-07)
    We study non-perturbative interpolating functions to probe the physics of anomalous dimensions associated with twist-two operators in SYM of finite and infinite spin. Compared to previous studies, the novel result of this ...
  • Entanglement entropy for TT deformed CFT in general dimensions 
    Banerjee, Aritra (Elsevier, 2019-11)
    We consider deformation of a generic d dimensional () large-N CFT on a sphere by a spin-0 operator which is bilinear in the components of the stress tensor. Such a deformation has been proposed to be holographically dual ...
  • The tensionless path from closed to open strings 
    Banerjee, Aritra (APS, 2019-09)
    We reconsider the tensionless limit on bosonic closed string theory, where the 3D Bondi-Metzner-Sachs (BMS) algebra appears as symmetries on the world sheet, as opposed to two copies of the Virasoro algebra in the case of ...
  • On N-spike strings in conformal gauge with NS-NS fluxes 
    Banerjee, Aritra (Springer, 2019)
    The AdS3 × S3 string sigma model supported both by NS-NS and R-R fluxes has become a well known integrable model, however a putative dual field theory description remains incomplete. We study the anomalous dimensions of ...
  • Cosmography and flat Λ⁢CDM tensions at high redshift 
    Banerjee, Aritra (APS, 2020-12)
    Risaliti, Lusso, and collaborators have constructed a high-redshift Hubble diagram of supernovae (SNe), quasars (QSO), and gamma-ray bursts (GRBs) that shows a “∼4⁢𝜎 tension with the Λ⁢CDM model” based on a log polynomial ...
