Charge and Color Breaking
The presence of scalar fields with color and electric charge in supersymmetric theories makes feasible the existence of dangerous charge and color breaking (CCB) minima and unbounded from below directions (UFB) in the effective potential, which would make the standard vacuum unstable. The avoidance of these occurrences imposes severe constraints on the supersymmetric parameter space. We give he...
متن کاملCalculating charge radius for proton with hyper central interacting color potential
An improved M.I.T. bag model with hyper central interaction is used to calculate the charge radius for proton containing u and d quarks. We present a theoretical approach to the internal structure of three-body hyper central interacting quarks in a proton, in which we take proton as a bag. We discuss a few of results obtained using a six-dimension potential, which is attractive for small separa...
متن کاملCharge and Color Breaking in Supersymmetry and Superstring
Charge and color breaking minima in SUSY theories might make the standard vacuum unstable. In this talk a brief review of this issue is performed. When a complete analysis of all the potentially dangerous directions in the field space of the theory is carried out, imposing that the standard vacuum should be the global minimum, the corresponding constraints turn out to be very strong and, in fac...

متن کاملSearch for color charge dependence of energy loss at RHIC
The non-Abelian feature of quantum chromodynamics (QCD) results in the gluons losing more energy than quarks in the medium formed in high energy heavy-ion collisions. Experimental results in p+p collisions when compared to NLO pQCD calculations show that at high transverse momentum (pT) the produced protons+anti-protons are dominantly from gluon jets and charged pions have substantial contribut...
