Probing chiral and flavored $$Z^\prime $$ Z ′ from cosmic bursts through neutrino interactions

Abstract

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 $$Z^\prime $$ Z ′ is evolved. To explore the properties of its interactions we consider chiral (flavored) frameworks where $$Z^\prime $$ Z ′ interactions depend on the handedness (generations) of the fermions. In this paper we focus on $$Z^\prime $$ Z ′ -neutrino interactions which could be probed from cosmic explosions. We consider $$\nu \overline{\nu } \rightarrow e^+ e^-$$ ν ν ¯ → 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 $$(g_X)$$ ( g X ) and $$Z^\prime $$ Z ′ mass $$(M_{Z^\prime })$$ ( M Z ′ ) under Schwarzchild (Sc) and Hartle-Thorne (HT) scenarios. We also study $$\nu $$ ν -DM scattering through $$Z^\prime $$ Z ′ to constrain $$g_X-M_{Z^\prime }$$ g X - M Z ′ plane using IceCube data considering high energy neutrinos from cosmic blazar (TXS0506+056), active galaxy (NGC1068), the Cosmic Microwave Background (CMB) and the Lyman- $$\alpha $$ α data, respectively. Finally highlighting complementarity we compare our results with current and prospective bounds on $$g_X-M_{Z^\prime }$$ g X - M Z ′ plane from scattering, beam-dump and $$g-2$$ g - 2 experiments.
