Hidden Glashow resonance in neutrino-nucleus collisions

Understand

Today it is widely believed that $s$-channel excitation of an on-shell~$W$ boson, commonly known as the Glashow resonance, can be initiated in matter only by the electron antineutrino in the process $\bar\nu_ee^-\rightarrow W^-$ at the laboratory energy around~6.3~PeV.

• In this paper we argue that the Glashow resonance within the Standard Model also occurs in neutrino--nucleus collisions.
• The main conclusions are as follows.
• 1)~The Glashow resonance can be excited by both~neutrinos and~antineutrinos of all the three flavors scattering in the Coulomb field of a nucleus.
