Accidental Peccei-Quinn Symmetry from Discrete Flavour Symmetry and Pati-Salam
Fredrik Björkeroth, Eung Jin Chun, Stephen F. King
We show how an accidental Peccei-Quinn (PQ) symmetry can arise from a discrete family symmetry combined with a discrete flavour symmetry $ \mathbb{Z}_3 \times \mathbb{…
Scalar Dark Matter in Leptophilic Two-Higgs-Doublet Model
Priyotosh Bandyopadhyay, Eung Jin Chun, Rusa Mandal
Two-Higgs-Doublet Model of Type-X in the large limit becomes leptophilic to allow a light pseudo-scalar and thus provides an explanation of the muon anomaly. Intr…
LSP baryogenesis and neutron-antineutron oscillations from R-parity violation
Lorenzo Calibbi, Eung Jin Chun, Chang Sub Shin
R-parity and baryon number violating operators can be allowed in the Supersymmetric Standard Model and thus lead to interesting baryon number violating processes such as neutron-an…
Reconstructing a light pseudoscalar in the Type-X Two Higgs Doublet Model
Eung Jin Chun, Siddharth Dwivedi, Tanmoy Mondal +1
We investigate the detectability as well as reconstructibility of a light pseudoscalar particle , of mass in the 50 - 60 GeV range, which is still allowed in a Type-X (lepton-sp…
Implications of right-handed neutrinos in extended standard model with scalar dark matter
Priyotosh Bandyopadhyay, Eung Jin Chun, Rusa Mandal
We investigate the Standard Model (SM) with a gauge extension where a charged scalar is a viable dark matter (DM) candidate. The dominant annihilation process, f…
