Analytic regularization of the Yukawa Model at Finite Temperature
We analyse the one-loop fermionic contribution for the scalar e ective potential in the temperature dependent Yukawa model. In order to regularize the model a mix between dimensional and analytic regularization procedures is used. We nd a general expression for the fermionic contribution in arbitrary spacetime dimension. It is found that in D = 3 this contribution is nite. Pacs number: 11.10.Ef...
متن کاملTowards Selecting a Finite - Range Regularization Scale
Received (received date) Revised (revised date) Extensive studies have demonstrated that finite-range regularization (FRR) offers significantly improved chiral extrapolations for lattice QCD. These studies have typically relied on selecting the finite-regularization scale based upon phenomenological input. Here we report on a preliminary investigation of a procedure to determine a preferred ran...
متن کاملFinite Temperature Effective Theories
High-temperature and dense matter of elementary particles appears in several areas of physics. The rst and most familiar example is the Universe at the early stages of its expansion. The Big Bang theory (for reviews see, e.g. ) states that the Universe was hot and dense in the past, with a temperature ranging from a few eV up to the Planck scale MPl 10 GeV. Another place, where matter exists in...
متن کاملQuarkonium at Finite Temperature
There was considerable interest in the properties and the fate of heavy quarkonium states at finite temperature since the famous conjecture by Matsui and Satz [1]. It has been argued that color screening in medium will lead to quarkonium dissociation above deconfinement, which in turn can signal quark gluon plasma formation in heavy ion collisions. The basic assumption behind the conjecture by ...
متن کاملFinite Temperature Strings ∗
In this talk a review of earlier work on finite temperature strings was presented. Several topics were covered, including the canonical and microcanonical ensemble of strings, the behavior of strings near the Hagedorn temperature as well as speculations on the possible phases of high temperature strings. The connection of the string ensemble and, more generally, statistical systems with an expo...
