Can INO be sensitive to flavor-dependent long-range forces?

Abstract

Flavor-dependent long-range leptonic forces mediated by the ultra-light and neutral bosons associated with gauged L e − L µ or L e − L τ symmetry constitute a minimal extension of the Standard Model. In presence of these new anomaly free abelian symmetries, the SM remains invariant and renormalizable, and can lead to interesting phenomenological consequences. For an example, the electrons inside the Sun can generate a flavor-dependent long-range potential at the Earth surface, which can enhance ν µ andν µ survival probabilities over a wide range of energies and baselines in atmospheric neutrino experiments. In this paper, we explore in detail the possible impacts of these long-range flavor-diagonal neutral current interactions due to L e − L µ and L e − L τ symmetries (one at-a-time) in the context of proposed 50 kt magnetized ICAL detector at INO. Combining the information on muon momentum and hadron energy on an event-by-event basis, ICAL can place stringent constraints on the effective gauge coupling α eµ/eτ < 1.2 × 10 −53 (1.75 × 10 −53 ) at 90% (3σ) C.L. with 500 kt·yr exposure. The 90% C.L. limit on α eµ (α eτ ) from ICAL is ∼ 46 (53) times better than the existing bound from the Super-Kamiokande experiment.

The νR-philic scalar: its loop-induced interactions and Yukawa forces in LIGO observations

“…[25][26][27] is a pseudo-scalar boson, in this work we compute loop-induced interactions for a generic scalar and take three lepton flavors into account, with loop calculation details presented. The loop-induced interactions computed in this work could be of importance in phenomenological studies of long-range forces [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46].…”

Wolfenstein potentials for neutrinos induced by ultra-light mediators

“…The matter effects due to light mediators have been studied before [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The mediators, mostly considered in the literature, are new gauge bosons of the lepton numbers L e −L µ , L µ −L τ or L τ −L e .…”

Probing Lorentz Invariance Violation with atmospheric neutrinos at INO-ICAL

“…Using this good detector response, the ICAL Collaboration has performed various analyses involving standard oscillations using JHEP03(2022)050 atmospheric neutrino [78,[81][82][83][84][85][86][87][88][89][90]. ICAL provides a unique avenue to probe a plethora of BSM scenarios [49,53,[91][92][93][94][95][96][97][98]. In the context of searching the signature of CPT violation at ICAL, a dedicated work has been performed in ref.…”
