Effective Theories for QCDlike at TeV Scale
(2016) In Nuclear and Particle Physics Proceedings 273275. p.16181623 Abstract
We study the Effective Field Theory of three QCDlike theories, which can be classified by having quarks in a complex, real or pseudoreal representations of the gauge group. The Lagrangians are written in a very similar way so that the calculations can be done using techniques from Chiral Perturbation Theory (ChPT). We calculated the vacuumexpectationvalue, the mass and the decay constant of pseudoGoldstone Bosons up to nexttonextto leading order (NNLO) [1]. The various channels of general n flavour mesonmeson scattering of the three theories are systematically studied and calculated up to NNLO [2]. We also calculated the vector, axialvector, scalar, pseudoscalar twopoint functions and pseudoscalar decay constant up NNLO... (More)

We also calculated the vector, axialvector, scalar, pseudoscalar twopoint functions and pseudoscalar decay constant up NNLO order [3]. The analytic expressions of the S parameter for the three different QCDlike theories are obtained at TeV scale. Our results are useful for chiral extrapolation in lattice calculation on theory of strong dynamical and finite baryon density.
