    "abstract": "We derive the leading contribution to the four-nucleon force within the\nframework of chiral effective field theory. It is governed by the exchange of\npions and the lowest-order nucleon-nucleon contact interaction and includes\neffects due to the nonlinear pion-nucleon couplings and the pion self\ninteractions constrained by the chiral symmetry of QCD. The resulting\nfour-nucleon force does not contain any unknown parameters and can be tested in\nfew- and many-nucleon studies.",
