Constraining ALP-Meson overlaps from form factors
Triparno Bandyopadhyay, Subhajit Ghosh
We present the first constraints on the overlaps between an Axion-like particle (ALP) and the and mesons from the analysis of the distortions to the $\langle K|\overline{…
Potential for the discovery of the protophobic boson at the STCF
Althaf M., Triparno Bandyopadhyay
We study the morphology of the main drift chamber (MDC) to be built around the collision point of the proposed Super tau-charm facility (STCF), to check its suitability for discove…
Dark Photons from displaced vertices
Triparno Bandyopadhyay
We investigate the unexplored regions of the dark photon parameter space to find a search strategy suitable to probe these. We show how displaced track searches at colliders with l…
A twisted tale of the transverse-mass tail
Triparno Bandyopadhyay, Ankita Budhraja, Samadrita Mukherjee +1
We propose a tantalizing possibility that misinterpretation of the reconstructed missing momentum may have yielded the observed discrepancies among measurements of the -mass in…
Signatures of generalized ALP interactions in SM decays of mesons
Subhajit Ghosh, Triparno Bandyopadhyay, Tuhin S. Roy
In addition to giving rise to spectacular new physics signals in the final states of meson decays, Axion-like-particles also induce modifications in the standard model decays of me…
Displaced Searches for Light Vector Bosons at Belle II
Triparno Bandyopadhyay, Sabyasachi Chakraborty, Sokratis Trifinopoulos
With a design luminosity of 50 ab and detectors with tracking capabilities extending beyond 1 m, the Belle II experiment is the perfect laboratory for the search of particle…
ALP-Pions generalized
Triparno Bandyopadhyay, Subhajit Ghosh, Tuhin S. Roy
A light axion-like particle or an ALP not just gives rise to interesting and spectacular signals of new physics as final states in meson decays, it necessarily leaves tell-tale sig…
The E6 route to multicomponent dark matter
Triparno Bandyopadhyay, Rinku Maji
We present a framework of dark- and visible-sector unification in the E6 embedding of the standard model. The demand for consistently getting the standard model leads to the existe…
Complementary bound on mass from Higgs to diphoton decay
Triparno Bandyopadhyay, Dipankar Das, Roman Pasechnik +1
Using the left-right symmetric model as an illustrative example, we suggest a simple and straightforward way of constraining the mass directly from the decay of the Higgs boso…
A reappraisal of constraints on models from unitarity and direct searches at the LHC
Triparno Bandyopadhyay, Gautam Bhattacharyya, Dipankar Das +1
In a truly model-independent approach, we reexamine a minimal extension of the Standard Model (SM) through the introduction of an additional symmetry leading to a new neutra…
Left-right model with TeV fermionic dark matter and unification
Triparno Bandyopadhyay, Amitava Raychaudhuri
The ingredients for a model with a TeV right-handed scale, gauge coupling unification, and suitable dark matter candidates lie at the heart of left-right symmetry with broken D-par…
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…
