Abstract Exotic spin-0 states with unusual couplings with the gauge and matter fields of the Standard Model are worth exploring at the CERN LHC. Though our approach is largely model independent, we take inspiration from flavor models based on some di

Abstract The current upper limit on $$N_\textrm{eff}$$ N eff at the time of CMB by Planck 2018 can place stringent constraints in the parameter space of BSM paradigms where their additional interactions may affect neutrino decoupling. Motivated by th

The EW-νR model was constructed in order to provide a seesaw scenario operating at the Electroweak scale ΛEW∼246 GeV, keeping the same SM gauge structure. In this model, right-handed neutrinos are non-sterile and have masses of the order ΛEW. Th

Abstract The relic density of Dark Matter (DM) in the freeze-in scenario is highly dependent on the evolution history of the universe and changes significantly in a non-standard (NS) cosmological framework prior to Big Bang Nucleosynthesis (BBN). In

Abstract A color octet isodoublet can have esoteric origins and it complies with minimal flavour violation. In this study, we take a scenario where the well known Type-X Two-Higgs doublet model is augmented with a color octet isodoublet. We shed ligh

Abstract We investigate the phenomenology of a non-thermal dark matter (DM) candidate in the context of flavor models that explain the hierarchy in the masses and mixings of quarks and leptons via the Froggatt-Nielsen (FN) mechanism. A flavor-depende

Abstract In this work, we explore the signals of an $$S_3$$ S 3 -symmetric two Higgs doublet model with two generations of vector-like leptons (VLLs) at the proposed International Linear Collider (ILC). The lightest neutral component of the VLL in th

Abstract We study the $$S_3$$ S 3 -symmetric two Higgs doublet model by adding two generations of vector like leptons (VLL) which are odd under a discrete $$Z_2$$ Z 2 -symmetry. The lightest neutral component of the VLL acts as a dark matter (DM) whe

Abstract Color-octet scalars arise in various Grand Unification scenarios and also in other models of new physics. They are also postulated for minimal flavour violation. Purely phenomenological imprints of such scalars are therefore worth looking at

Mandarin orange is economically one of the most important fruit crops in Bhutan. However, in recent years, orange productivity has dropped due to severe infection of citrus tristeza virus (CTV) associated with the gradual decline of citrus orchards.
