The Chiral Phase Transition in Lattice QCD with Domain-Wall Fermions |
|
|
Content: |
Chiral symmetry plays an important role in determining the nature of the
strong interactions. It is spontaneously broken at $T=0$ but restored above
a certain temperature $T_c$. To study this transition on the lattice, it is
crucial to use a discretization scheme that preserves chiral symmetry.
In this talk, we shall present preliminary results of a detailed study of the
chiral phase transition with Domain Wall Fermions (DWF). Our simulations are
2+1-flavor simulations on lattices of size $16^3 \times 8$ with a fifth
dimension of $L_s=32$ and $48$. The strange quark mass is tuned to its
physical value and light quark masses are choosen such that the pion mass is
fixed at $m_\pi=200$ MeV.
We present results in the temperature range $140\leq T\leq 190$ MeV for the
disconnected light quark chiral susceptibility ($\chi_\text{disc}$) as well
as the light pseudoscalar, vector and axial-vector screening lengths. We
analyze signatures for the QCD transition temperature arising from a peak in
the susceptibility, a rise in the pseudoscalar screening length and the
degeneracy of vector and axial-vector screening lengths. |
