Approaching the Chiral and Continuum Limit of Large-N QCD
May 16, 2022
We present preliminary results from our calculation of the low energy constants (LECs) of the chiral effective theory for 3, 4 and 5 color QCD with $N_f = 2$ dynamical fermion flavors. We simulate with clover fermions over a range of lattice couplings and quark masses. We observe the expected 𝑁𝑐 scaling for the LECs appropriate to the condensate 𝐵 and pseudoscalar decay constant 𝐹. The range of quark masses over which leading order chiral perturbation theory describes the data grows as 𝑁𝑐 rises.
