    "abstract": "We calculate at two-loop order in chiral perturbation theory the\nelectromagnetic corrections to the dominant two-pion exchange nucleon-nucleon\ninteraction that is generated by the isoscalar $\\pi N$ contact-vertex\nproportional to the large low-energy constant $c_3$. We find that the\nrespective $2\\pi\\gamma$-exchange potential contains sizeable isospin-breaking\ncomponents which amount to about -1% of the strongly attractive isoscalar\ncentral $2\\pi$-exchange potential. The typical value of these novel\ncharge-independence and charge-symmetry breaking central potentials is $0.3\n$MeV at a nucleon distance of $r= m_\\pi^{-1} = 1.4 $fm. Our analytical result\nfor this presumably dominant $2\\pi\\gamma$-exchange interaction is in a form\nsuch that it can be easily implemented into phase-shift analyses and few-body\ncalculations.",
