Lorentz violation andαdecay
Relating the effective Lorentz violation coefficients for composite particles to the coefficients for their constituent fields is a challenging problem. We calculate the Lorentz violation coefficients relevant to the dynamics of an a particle in terms of proton and neutron coefficients. The α-particle coefficients would lead to anisotropies in the a decays of nuclei, and because the decay process involves quantum tunneling, the effects of any Lorentz violations could be exponentially enhanced.
