Probing chiral and flavored \(Z^\prime \) from cosmic bursts through neutrino interactions

Abstract

The origin of tiny neutrino mass is an unsolved puzzle leading to a variety of phenomenological aspects beyond the Standard Model (BSM). We consider U(1) gauge extension of the Standard Model (SM) where so-called seesaw mechanism is incarnated with the help of thee generations of Majorana type right-handed neutrinos followed by the breaking of U(1) and electroweak gauge symmetries providing anomaly free structure. In this framework, a neutral BSM gauge boson \(Z^\prime \) is evolved. To explore the properties of its interactions we consider chiral (flavored) frameworks where \(Z^\prime \) interactions depend on the handedness (generations) of the fermions. In this paper we focus on \(Z^\prime \)-neutrino interactions which could be probed from cosmic explosions. We consider \(\nu \overline{\nu } \rightarrow e^+ e^-\) process which can energize gamma-ray burst (GRB221009A, so far the highest energy) through energy deposition. Hence estimating these rates we constrain U(1) gauge coupling \((g_X)\) and \(Z^\prime \) mass \((M_{Z^\prime })\) under Schwarzchild (Sc) and Hartle-Thorne (HT) scenarios. We also study \(\nu \)-DM scattering through \(Z^\prime \) to constrain \(g_X-M_{Z^\prime }\) plane using IceCube data considering high energy neutrinos from cosmic blazar (TXS0506+056), active galaxy (NGC1068), the Cosmic Microwave Background (CMB) and the Lyman-\(\alpha \) data, respectively. Finally highlighting complementarity we compare our results with current and prospective bounds on \(g_X-M_{Z^\prime }\) plane from scattering, beam-dump and \(g-2\) experiments. [PICS code].
