Scalar Dark Matter Probes the Scale of Non-locality
Anish Ghoshal
Scalar dark matter (DM) in a theory introduces hierarchy problems, and suffers from the inability to predict the preferred mass range for the DM. In a WIMP-like minimal scalar DM s…
Transmutation of nonlocal scale in infinite derivative field theories
Luca Buoninfante, Anish Ghoshal, Gaetano Lambiase +1
In this paper we will show an ultraviolet -infrared connection for ghost-free infinite derivative field theories where the Lagrangians are made up of exponentials of entire functio…
Inflation, (P)reheating and Neutrino Anomalies: Production of Sterile Neutrinos with Secret Interactions
Arnab Paul, Anish Ghoshal, Arindam Chatterjee +1
A number of experimental anomalies involving neutrinos hint towards the existence of at least an extra (a very light) sterile neutrino. However, such a species, appreciably mixing…
Resonant production of dark photons in positron beam dump experiments
Enrico Nardi, Cristian D. R. Carvajal, Anish Ghoshal +2
Positrons beam dump experiments have unique features to search for very narrow resonances coupled superweakly to pairs. Due to the continue loss of energy from soft photo…
