Superconformal Dynamics and SUSY Flavor Problem
We study the scenario leading to hierarchical Yukawa couplings and at the same time degenerate sfermion masses. Superconformal dynamics plays a role. Understanding the origin of fermion masses and mixing angles is one of most important issues in particle physics. Yukawa couplings are free parameters within the framework of the standard model (SM). There are several types of flavor mechanisms to...
متن کاملCharging the Superconformal Index
The superconformal index is an important invariant of superconformal field theories. In this note we refine the superconformal index by inserting the charge conjugation operator C. We construct a matrix integral for this charged index for N = 4 SYM with SU(N) gauge group. The key ingredient for the construction is a “charged character,” which reduces to Tr(C) for singlet representations of the ...
متن کاملSuperconformal Symmetries and Models
We discuss the following aspects of two-dimensional N = 2 supersymmetric theories defined on compact super Riemann surfaces: parametrization of (2, 0) and (2, 2) superconformal structures in terms of Beltrami coefficients and formulation of superconformal models on such surfaces (invariant actions, anomalies and compensating actions, Ward identities).
متن کاملFlavor without Flavor Symmetry
Non-trivial patterns of quark and lepton masses and mixings can arise without there being any underlying flavor symmetry that distinguishes among the three families. Two realistic examples are given.
متن کاملSuperconformal Hypermultiplets in Superspace
We use the manifestly N=2 supersymmetric, off-shell, harmonic (or twistor) superspace approach to solve the constraints implied by four-dimensional N=2 superconformal symmetry on the N=2 non-linear sigma-model target space, known as the special hyper-Kähler geometry. Our general solution is formulated in terms of a homogeneous (of degree two) function of unconstrained (analytic) Fayet-Sohnius h...
