Proton and neutron electromagnetic form factors using $N_f$=2+1+1 twisted-mass fermions with physical values of the quark masses

Constantia Alexandrou, Simone Bacchio, Giannis Koutsou +2

We compute the electromagnetic form factors of the proton and neutron using lattice QCD with $N_f=2+1+1$ twisted mass clover-improved fermions and quark masses tuned to their…
