| 11:00 - 12:00 Theory Weekly Seminar(TWS) Novel phase structures in Box^k scalar theories School PARTICLES AND ACCELERATORS I will first review the notion of functional perturbative renormalization group, and then discuss its application to scalar theories with higher-derivative kinetic terms. D epending on the upper critical dimension and the number of derivatives in the kinetic term two types of theories are distinguished which demonstrate qualitatively different features. We study the flow equations and critical properties of each type of models in turn. We show that while the first class of models is qualitatively similar to theories with standard kinetic term and admits a generalized Wilson-Fisher fixed point, in theories of the second type derivative interac ... |
