Operator relations and chemical effects on chiral dynamics in QCD
نویسنده
چکیده
We discuss effects of chemical potential on the dynamics of chiral transition by the Taylor expansion method in lattice QCD. Operators and their Taylor expansions which characterise the chiral dynamics are related through Maxwell’s relations and Chiral Ward identities. This reduces the computation to just measuring the renormalized expectation values of the chiral condensate and its Taylor coefficients. The various relations can then be used to extract information of the operators responsible for the characteristics of the chiral dynamics.

A random matrix model for chiral symmetry breaking
We formulate a random matrix model which mimics the chiral phase transition in QCD with two light flavors. Two critical exponents are calculated. We obtain the mean field values β = 1 2 and δ = 3. We also find that the chiral phase transition can be characterized by the dynamics of the smallest eigenvalue of the Dirac operator. This suggests an alternative order parameter which may be of releva...
متن کاملThe sign problem in the ε-regime of QCD
QCD in the ε-regime at nonzero baryon chemical potential µ is reviewed. The focus is on aspects of the sign problem which are relevant for lattice QCD. It is discussed how spontaneous chiral symmetry breaking and the sign problem are related through the spectrum of the Dirac operator. The strength of the sign problem is linked to the quark mass and the chemical potential. Specific implications ...
متن کاملQCD dirac operator at nonzero chemical potential: lattice data and matrix model.
Recently, a non-Hermitian chiral random matrix model was proposed to describe the eigenvalues of the QCD Dirac operator at nonzero chemical potential. This matrix model can be constructed from QCD by mapping it to an equivalent matrix model which has the same symmetries as QCD with chemical potential. Its microscopic spectral correlations are conjectured to be identical to those of the QCD Dira...
متن کاملPseudoscalar mesons and their radial excitations from the Effective Chiral Lagrangian
Effective Chiral Lagrangian is derived from QCD in the framework of Field Correlator Method. It contains the effects of both confinement and chiral symmetry breaking due to a special structure of the resulting quark mass operator. It is shown that this Lagrangian describes light pseudoscalar mesons, and Gell-Mann-OakesRenner relations for pions, eta and K mesons are reproduced. Spectrum of radi...
متن کاملLow Dirac Eigenmodes and the Topological and Chiral Structure of the Qcd Vacuum
Standard methods in lattice QCD consist of calculating various hadronic amplitudes by tying together appropriate combinations of quark propagators calculated on an ensemble of Monte Carlo generated gauge fields. A number of recent lattice QCD calculations have focused increasing attention on the role of low-lying eigenmodes of the Dirac operator in typical background gauge fields. The decomposi...
