Large-N_f behavior of the Yukawa model: analytic results
Sergio Caracciolo, Bortolo Matteo Mognetti, Andrea Pelissetto
We investigate the Yukawa model in which fermions are coupled with a scalar field through a Yukawa interaction. The phase diagram is rather well understood. If the fermio…
High-accuracy two-loop computation of the critical mass for Wilson fermions
Sergio Caracciolo, Andrea Pelissetto, Antonio Rago
We test an algebraic algorithm based on the coordinate-space method, evaluating with high accuracy the critical mass for Wilson fermions in lattice QCD at two loops. We test the re…
The pion_0 to gamma gamma decay and the chiral anomaly in the quark-composites approach to QCD
Sergio Caracciolo, Fabrizio Palumbo
We evaluate the pion_0 into two gammas decay amplitude by an effective action derived from QCD in the quark composites approach, getting the standard value. We also verify that our…
Bilocal Dynamics for Self-Avoiding Walks
Sergio Caracciolo, Maria Serena Causo, Giovanni Ferraro +2
We introduce several bilocal algorithms for lattice self-avoiding walks that provide reasonable models for the physical kinetics of polymers in the absence of hydrodynamic effects.…
Lattice QCD and chiral mesons
Sergio Caracciolo, Fabrizio Palumbo, Roberto Scimia
The standard QCD action is improved by the addition of irrelevant operators built with chiral composites. An effective Lagrangian is derived in terms of auxiliary fields, which has…
