# Roberge-Weiss endpoint in N{sub f}=2 QCD

@article{Bonati2010RobergeWeissEI, title={Roberge-Weiss endpoint in N\{sub f\}=2 QCD}, author={Claudio Bonati and Guido Cossu and Massimo D'Elia and Francesco Sanfilippo}, journal={Physical Review D}, year={2010}, volume={83} }

We present the results of extensive simulations regarding the critical behavior at the endpoint of the Roberge-Weiss transition for N{sub f}=2 QCD. We confirm early evidence, presented in Ref. [M. D'Elia and F. Sanfilippo, Phys. Rev. D 80, 111501(R) (2009).], according to which the Roberge-Weiss endpoint is first order in the limit of large or small quark masses, and second order for intermediate masses. A systematic study of the transition strength as a function of the quark mass in the first…
