Instantons and Meson Correlation Functions in QCD
Various QCD correlators are calculated in the instanton liquid model in zeromode approximation and 1/Nc expansion. Previous works are extended by including dynamical quark loops. In contrast to the original ”perturbative” 1/Nc expansion not all quark loops are suppressed. In the flavor singlet meson correlators a chain of quark bubbles survives the Nc →∞ limit causing a massive η′ in the pseudo...
متن کاملMeson correlation functions in a QCD plasma
The temporal pseudoscalar meson correlation function in a QCD plasma is investigated in a range of temperatures exceeding Tc and yet of experimental interest. Only the flavour-singlet channel is considered and the imaginary time formalism is employed for the finite temperature calculations. The behaviour of the meson spectral function and of the temporal correlator is first studied in the HTL a...
متن کاملFinite momentum meson correlation functions in a QCD plasma
The finite momentum meson spectral function (MSF) in the pseudoscalar channel is evaluated, adopting for the fermionic propagators HTL expressions. The different contributions to the meson spectral functions are clearly displayed. Our analysis may be of relevance for lattice studies of MSF based so far on the Maximum Entropy Method. As a further step the correlation function along the (imaginar...
متن کاملEfficient computation of meson and four-quark correlation functions
This work deals with the efficiency of different methods for computing correlation functions of bound states in twisted mass lattice QCD with Nf = 2 flavors of seaquarks. In particular, the focus will be on pseudo-scalar and scalar meson correlators as well as correlation functions generated by a four-quark operator. The main part of this thesis will be the comparison of three methods used to c...
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 ...
