Screened Perturbation Theory to Three Loops
The thermal physics of a massless scalar field with a φ interaction is studied within screened perturbation theory (SPT). In this method the perturbative expansion is reorganized by adding and subtracting a mass term in the lagrangian. We consider several different mass prescriptions that generalize the one-loop gap equation to two-loop order. We calculate the pressure and entropy to three-loop...
متن کاملScreened perturbation theory at four loops
We study the thermodynamics of massless φ-theory using screened perturbation theory, which is a way to systematically reorganise the perturbative series. The free energy and pressure are calculated through four loops in a double expansion in powers of g and m/T , where m is a thermal mass of order gT . The result is truncated at order g. We find that the convergence properties are significantly...
متن کاملScreened Perturbation Theory
A new perturbative scheme is proposed for the evaluation of the free energy density of field theories at finite temperature. The screened loop expansion takes into account exactly the phenomenon of screening in thermal propagators. The approach is tested in the N -component scalar field theory at 2-loop level and also at 3-loop in the large N limit. The perturbative series generated by the scre...
متن کاملMass Expansions of Screened Perturbation Theory
The thermodynamics of massless φ4-theory is studied within screened perturbation theory (SPT). In this method the perturbative expansion is reorganized by adding and subtracting a mass term in the Lagrangian. We analytically calculate the pressure and entropy to three-loop order and the screening mass to two-loop order, expanding in powers of m/T . The truncated m/T -expansion results are compa...
متن کاملFermionic Loops in Numerical Stochastic Perturbation Theory
In recent years the Numerical implementation of Stochastic Perturbation Theory (NSPT) was introduced, which was able to reach unprecedented high orders in perturbative expansions in Lattice Gauge Theories (LGT). Till now the main limitation of the method has been the quenched approximation, an inclusion of fermionic loops contributions missing. We can now fill this gap. Let us first of all remi...
