Testing the principle of equivalence by solar neutrinos.
We discuss the possibility of testing the principle of equivalence with solar neutrinos. If there exists a violation of the equivalence principle quarks and leptons with different flavors may not universally couple with gravity. The method we discuss employs a quantum mechanical phenomenon of neutrino oscillation to probe into the non-universality of the gravitational couplings of neutrinos. We...
متن کاملThe Solar Test of the Equivalence Principle
The Earth, Mars, Sun, Jupiter system allows for a sensitive test of the strong equivalence principle (SEP) which is qualitatively different from that provided by Lunar Laser Ranging. Using analytic and numerical methods we demonstrate that Earth-Mars ranging can provide a useful estimate of the SEP parameter η. Two estimates of the predicted accuracy are derived and quoted, one based on convent...
متن کاملHigh-energy cosmic neutrinos and the equivalence principle.
Observation of ultra-high energy neutrinos, in particular detection of ντ , from cosmologically distant sources like active galactic nuclei (AGN) opens new possibilities to search for neutrino flavor conversion. We consider the effects of violation of the equivalence principle (VEP) on propagation of these cosmic neutrinos. In particular, we discuss the two effects: (1) the oscillations of neut...
متن کاملTesting the principle of equivalence by supernova neutrinos
We study the possible impact of the neutrino oscillation which could be induced by a tiny violation of equivalence principle (VEP) for neutrinos emitted from supernova driven by gravitational collapse. Due to the absence of any significant indication of neutrino oscillation in the SN1987A data, we obtain sever bounds on relevant VEP parameters δγ ∼ O(10−31) for massless or degenerated neutrinos...
متن کاملPossible violation of the equivalence principle by neutrinos.
We consider the effect of a long range, flavor changing tensor interaction of possible gravitational origin. Neutrino mixing experiments provide the most sensitive probe to date for such forces—testing the equivalence principle at levels below 10 −20. Here we justify and generalize a formalism for describing such effects. The constraints from neutrino mixing experiments on gravitationally induc...
