Abstract: (arXiv)

We present studies of universal properties of the chiral phase transition in

N_f

=2+1 QCD based on the simulations using Highly Improved Staggered fermions on lattices with temporal extent

N_\tau

=6. We analyze the quark mass and volume dependence of the chiral condensates and chiral susceptibilities in QCD with two degenerate light quarks and a strange quark. The strange quark mass is chosen to be fixed to its physical value (

m^{phy}_s

) and five values of light quark masses (

m_l

) that are varied in the interval 1/20

\gtrsim m_l/m^{phy}_s \gtrsim

1/80. Here various quark masses correspond to pseudo Goldstone pion masses ranging from about 160 MeV to about 80 MeV. The O(N) scaling of chiral observables and the influence of universal scaling on physical observables in the region of physical quark mass values are also discussed.
