OPE of the energy-momentum tensor correlator in massless QCD
Abstract: We analytically calculate higher order corrections to coefficient functions of the operator product expansion (OPE) for the Euclidean correlator of two energy-momentum tensors in massless QCD. These are the three-loop contribution to the coefficient C0 in front of the unity operator O0 = 1 and the one and two-loop contributions to the coefficient C1 in front of the gluon “condensate” ...
متن کاملVery low energy matching of effective meson theories with QCD
A simple matching procedure is proposed to extract constraints on effective meson theories. In this way, a QCD prediction for the pion decay constant is found, Fπ = 2mπ/π ≈ 90 MeV. The same procedure also determines other mesonic observables, like the decay width of the sigma meson to two photons. Finally, some information which can be gained about the hadronic light-by-light contributions to t...
متن کاملOn Non-renormalization and OPE in Superconformal Field Theories
The OPE of two N = 2 R-symmetry current (short) multiplets is determined by the possible superspace three-point functions that two such multiplets can form with a third, a priori long multiplet. We show that the shortness conditions on the former put strong restrictions on the quantum numbers of the latter. In particular, no anomalous dimension is allowed unless the third supermultiplet is an R...

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
15 صفحه اولDynamics in the Conformal Window in QCD like Theories
Recently, there has been considerable interest in the existence of a nontrivial conformal dynamics in 3+1 dimensional non-supersymmetric vector like gauge theories, with a relatively large number of fermion flavors Nf [1–6]. The roots of this problem go back to a work of Banks and Zaks [7] who were first to discuss the consequences of the existence of an infrared-stable fixed point α = α∗ for N...
