Effects of physics beyond the standard model on the neutrino charge radius: an effective Lagrangian approach

H. Novales--S\' anchez, A. Rosado, V. Santiago--Ol\' an +1

In this work, we look for possible new physics effects on the electromagnetic charge and anapole form factors, $f_Q(q^2)$ and $f_A(q^2)$, for a massless Dirac neutrino, when these…
