We examine the compressed mass spectrum with sub-TeV top squark as lightest colored (s)particle in natural supersymmetry (SUSY). Such spectra are searched along with an additional hard jet, not only to boost the soft decay ...

Within a multicomponent dark matter scenario, novel gamma-ray signals may arise from the decay of the heavier dark matter component into the lighter. For a scalar dark sector of this kind, the decay ϕ2→ϕ1 γ is forbidden ...

We consider vectorlike quarks in a leptophobic 221 model characterized by the gauge group 𝑆⁢𝑈⁢(2)𝐿×𝑆⁢𝑈⁢(2)2×𝑈⁢(1)𝑋, where the 𝑆⁢𝑈⁢(2)2 is leptophobic in nature. We discuss the pattern of mixing between Standard ...

If the recent detection of B-mode polarization of the Cosmic Microwave Background by BICEP2 observations, withstand the test of time after the release of recent PLANCK dust polarisation data, then it would surprisingly put ...

We analyze the prospects of reconstructing the mass of a heavy charged Higgs boson in the context of a type X two-Higgs-doublet model where a light pseudoscalar 𝐴 in the mass range 40–60 GeV is phenomenologically allowed, ...

We consider two theoretical scenarios, each including a ℤ2-odd sector and leading to an elementary dark matter candidate. The first one is a variant of the Type-III seesaw model where one lepton triplet is ℤ2-odd, together ...

The CP violating two-Higgs doublet model of type-X may enhance significantly the electric and magnetic moment of leptons through two-loop Barr-Zee diagrams. We analyze the general parameter space of the type-X 2HDM consistent ...

Recently the study of anomalous gamma-ray emission in the regions surrounding the galactic center has drawn a lot of attention as it points out that the excess of gamma-ray in the low latitude is consistent with the emission ...

We study the 𝐵−𝐿 gauge extension of the Standard Model which contains a singlet scalar and three right-handed neutrinos. The vacuum expectation value of the singlet scalar breaks the 𝑈⁢(1)𝐵−𝐿 symmetry. Here the ...

The absolute stability of a dark matter (DM) particle is not a binding requirement. Here we suggest a few scenarios where the DM particle is liable to decay via extremely feeble interactions. This can happen via inexplicably ...
