Looking for an Invisible Higgs Signal at the LHC
Diptimoy Ghosh, Rohini Godbole, Monoranjan Guchait +2
While the recent discovery of a Higgs-like boson at the LHC is an extremely important and encouraging step towards the discovery of the {\it complete} standard model(SM), the curre…
Searching the sbottom in the four lepton channel at the LHC
Diptimoy Ghosh, Dipan Sengupta
Direct searches at the Large Hadron Collider (LHC) have pushed the lower limits on the masses of the gluinos () and the squarks of the first two generations (…
How large can the branching ratio of be ?
Amol Dighe, Diptimoy Ghosh
Motivated by the large like-sign dimuon charge asymmetry observed recently, whose explanation would require an enhanced decay rate of , we explore how large a bran…
Diagnosing New Physics in decays in the light of the recent BaBar result
Alakabha Datta, Murugeswaran Duraisamy, Diptimoy Ghosh
The BaBar Collaboration has recently reported the measurement of the ratio of the branching fractions of to $\bar{B} \to D(D^{*}) \ell^{-} \b…
How Constrained is the cMSSM?
Diptimoy Ghosh, Monoranjan Guchait, Sreerup Raychaudhuri +1
We study the allowed parameter space of the constrained minimal supersymmetric Standard Model (cMSSM) in the light of direct searches, constraints from -physics (including the r…
Large mass splittings for fourth generation fermions allowed by LHC Higgs exclusion
Amol Dighe, Diptimoy Ghosh, Rohini M. Godbole +1
In the context of the Standard model with a fourth generation, we explore the allowed mass spectra in the fourth generation quark and lepton sectors as functions of the Higgs mass.…
Magic Messengers in Gauge Mediation and signal for 125 GeV boosted Higgs boson
Pritibhajan Byakti, Diptimoy Ghosh
We consider a renormalizable messenger sector with magic messenger fields instead of usual SU(5) complete multiplets. We derive the soft supersymmetry breaking terms and show that…
Exploring New Physics in C_7-C_7'
S. Descotes-Genon, D. Ghosh, J. Matias +1
We discuss the model dependence in the determination of the Wilson coefficient C_7 that governs the radiative electromagnetic decays of B mesons in the Standard Model, by consideri…
Higgs signal in Chargino-Neutralino production at the LHC
Diptimoy Ghosh, Monoranjan Guchait, Dipan Sengupta
We have analyzed the prospect of detecting a higgs signal in mSUGRA/CMSSM based Supersymmetric(SUSY) model via chargino-neutralino($\CH_1\N0_2$) production at 8 TeV and 14 TeV LHC…
