Sensitivity of KM3NeT to Violation of Equivalence Principle

Equivalence Principle parity violation tests

Gravitation is parity symmetric or antisymmetric. Mass distribution parity divergence varies from χ = 0 (achiral) to χ = 1 (perfect). A parity Eötvös experiment contrasts chemically and macroscopically identical enantiomorphic space groups P3121 and P3221 α-quartz single crystal test masses. A parity calorimetry experiment contrasts P3121 and P3221 benzil single crystals’ enthalpies of fusion. ...

Neutrino mixing due to a violation of the equivalence principle.

Massless neutrinos will mix if their couplings to gravity are flavor dependent, i.e., violate the principle of equivalence. Because the gravitational interaction grows with neutrino energy, the solar neutrino problem and the recent atmospheric neutrino data may be simultaneously explained by violations at the level of 10 to 10 or smaller. This possibility is severely constrained by present acce...

Dark-Matter-Induced Weak Equivalence Principle Violation

Dark-matter-induced violation of the weak equivalence principle.

A long-range fifth force coupled to dark matter can induce a coupling to ordinary matter if the dark matter interacts with standard model fields. We consider constraints on such a scenario from both astrophysical observations and laboratory experiments. We also examine the case where the dark matter is a weakly interacting massive particle, and derive relations between the coupling to dark matt...

Violation of the Equivalence Principle in String Dilaton Theories

We study violations of the weak equivalence principle in the context of string dilaton theories. In these models some fundamental constants become spaceas well as time-dependent. We show that although universality of free fall (UFF) experiments set bounds on parameters that govern the cosmological evolution of the scalar fields, these are strongly relaxed when considering the space dependent be...
