Charged Higgs effects in IceCube: PeV events and NSIs
Ujjal Kumar Dey, Newton Nath, Soumya Sadhukhan
Extensions of the Standard Model with charged Higgs, having a non-negligible coupling with neutrinos, can have interesting implications vis-à-vis neutrino experiments. Such models…
Neutrino Floor in Leptophilic Models: Modification in
Soumya Sadhukhan, Manvinder Pal Singh
In this work, we investigate the beyond standard model (BSM) impact of leptophilic U(1) models, namely , and on coherent elastic…
Neutrino and phenomenology in an anomaly-free extension: role of higher-dimensional operators
Debajyoti Choudhury, Kuldeep Deka, Tanumoy Mandal +1
We consider an anomaly-free extension of the Standard Model with three right-handed neutrinos (RHNs) and two complex scalars, wherein the charge assignments preclud…
Discussing 125 GeV and 95 GeV excess in Light Radion Model
Divya Sachdeva, Soumya Sadhukhan
Even if the LHC observations are consistent with the Standard model (SM), current LHC results are not precise enough to rule out the presence of new physics. Taking a contrarian vi…
Probing the inert doublet model using jet substructure with a multivariate analysis
Akanksha Bhardwaj, Partha Konar, Tanumoy Mandal +1
We explore the challenging but phenomenologically interesting hierarchical mass spectrum of the Inert Doublet Model where relatively light dark matter along with much heavier scala…
Cutoff of IceCube Neutrino Spectrum due to t-channel Resonant Absorption by CB
Subhendra Mohanty, Ashish Narang, Soumya Sadhukhan
The non-observation of neutrinos by the IceCube at the Glashow resonance energy of 6.3 PeV has been a long standing unresolved issue. In this paper we propose a t-channel neutrino…
