Diphoton excess at 750 GeV: Singlet scalars confront triviality
Indrani Chakraborty, Anirban Kundu
We suggest that the recently observed diphoton excess at 750 GeV comes from a quasi-degenerate bunch of gauge singlet scalars produced and decaying through one or more vector-like…
Potential of a singlet scalar enhanced Standard Model
Swagata Ghosh, Anirban Kundu, Shamayita Ray
We investigate the parameter space of the Standard Model enhanced by a gauge singlet real scalar . Taking into account all the theoretical and experimental constraints, we show…
Rare Z Decays and Neutrino Flavor Universality
Gauthier Durieux, Yuval Grossman, Matthias König +2
We study rare four-body decays of the Z-boson involving at least one neutrino and one charged lepton. Large destructive interferences make these decays very sensitive to the Z coup…
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…
Implications of the CMS search for W_R on Grand Unification
Triparno Bandyopadhyay, Biswajoy Brahmachari, Amitava Raychaudhuri
The CMS experiment at the Large Hadron Collider has reported a 2.8 excess in the channel around 2.1 TeV. Interpretation of this data is reconsidered in terms of th…
A4-based see-saw model for realistic neutrino masses and mixing
Soumita Pramanick, Amitava Raychaudhuri
We present an -based model where neutrino masses arise from a combination of see-saw mechanisms. The model is motivated by several small mixing and mass parameters indicated by…
