Softly Broken N = 1 Supersymmetric QCD

چکیده
We study softly broken N = 1 supersymmetric QCD with the gauge group SU(Nc) and Nf flavours of quarks for Nf > Nc + 1. We investigate the phase structure of its dual theory adding generic soft supersymmetry breking terms, i.e. soft scalar masses, trilinear coupling terms of scalar fields and gaugino masses. It is found that the trilinear coupling terms play an improtant role in determining the potential minima. Also we compare softly broken original and dual theories in the broken phase. e-mail: [email protected] e-mail: [email protected] e-mail: [email protected]

Further All-loop Results in Softly-broken Supersymmetric Gauge Theories
It is proven that the recently found, renormalization-group invariant sum rule for the soft scalar masses in softly-broken N = 1 supersymmetric gauge-Yukawa unified theories can be extended to all orders in perturbation theory. In the case of finite unified theories, the sum rule ensures the all-loop finiteness in the soft supersymmetry breaking sector. As a byproduct the exact β function for t...
متن کاملNon-abelian Monopoles, Vortices and Confinement
Three closely related issues will be discussed. Magnetic quarks having non-Abelian charges have been found recently to appear as the dominant infrared degrees of freedom in some vacua of softly broken N = 2 supersymmetric QCD with SU(nc) gauge group. Their condensation upon N = 1 perturbation causes confinement and dynamical symmetry breaking. We argue that these magnetic quarks can be naturall...
متن کاملInfrared Behaviour of Softly Broken Sqcd and Its Dual
Applying the recently obtained results on the renormalization of soft supersymmetry-breaking parameters, we investigate the infrared behaviour of the softly broken supersymmetric QCD as well as its dual theory in the conformal window. Under general assumptions on βfunctions, it is shown that the soft supersymmetry-breaking parameters asymptotically vanish in the infrared limit so that superconf...
متن کاملSoftly Broken SQCD: in the Continuum, on the Lattice, on the Brane
We review progress in studying the solutions of SQCD in the presence of explicit, soft SUSY breaking terms. Massive N=1 SQCD in the presence of a small gaugino mass leads to a controlled solution which has interesting phase structure with changing θ angle reminiscent of the QCD chiral Lagrangian. Current attempts to test the solutions of pure glue SQCD on the lattice require a theoretical under...
متن کاملNon - universal corrections to the tension ratios in softly broken N = 2 SU ( N ) gauge theory Roberto
Calculation by Douglas and Shenker of the tension ratios for vortices of different N -alities in the softly broken N = 2 supersymmetric SU(N) Yang-Mills theory, is carried to the second order in the adjoint multiplet mass m. Corrections to the ratios violating the well-known sine formula are found, showing that it is not a universal quantity. 1. Recently the tension ratios among the confining v...
