Abnormal dilepton yield from parity breaking in dense nuclear matter
Alexander Andrianov, Vladimir Andrianov, Domenec Espriu +1
At finite density parity can be spontaneously broken in strong interactions with far reaching implications. In particular, a time-dependent pseudoscalar background would modify QED…
Abnormal dilepton yield from local parity breaking in heavy-ion collisions
Alexander Andrianov, Vladimir Andrianov, Domenec Espriu +1
We propose a novel explanation for the dilepton excess observed in heavy ion collisions at invariant masses below 1 GeV. We argue that the presence of local parity breaking due to…
Axions and Cosmic Rays
Domenec Espriu, Albert Renau
We investigate the propagation of a charged particle in a spatially constant but time dependent pseudoscalar background. Physically this pseudoscalar background could be provided b…
Axions and high-energy cosmic rays: Can the relic axion density be measured?
D. Espriu, F. Mescia, A. Renau
In a previous work we investigated the propagation of fast moving charged particles in a spatially constant but slowly time dependent pseudoscalar background, such as the one provi…
