Transition Temperature of Lattice Quantum Chromodynamics with Two Flavors with a Small Chemical Potential

We present the results for the transition temperature of quantum chromodynamics with two degenerate flavors (N_f=2) of Wilson quarks as a function of a small baryon chemical potential μ_B from Monte Carlo simulations at κ=0.175, κ is the hopping parameter. By using the imaginary chemical potential for which the fermion determinant is positive and the Ferrenberg-Swendsen reweighting method, we perform simulations on lattice 8³×4 with 4 being the temporal extent. By analytic continuation of the data to the real chemical potential μ, we obtain the transition temperature for the small chemical potential, and compare our results with others.
