The Weak Ope and Dimension - Eight Operators
We discuss recent work which identifies a potential flaw in standard treatments of weak decay amplitudes , including that of ǫ ′ /ǫ. The point is that (contrary to conventional wisdom) dimension-eight operators contribute to weak amplitudes at order G F αs and without 1/M 2 W suppression. The effect of dimension-eight operators is estimated to be at the 100% level in a sum rule determination of...
متن کاملBounds for the dimension of the $c$-nilpotent multiplier of a pair of Lie algebras
In this paper, we study the Neumann boundary value problem of a class of nonlinear divergence type diffusion equations. By a priori estimates, difference and variation techniques, we establish the existence and uniqueness of weak solutions of this problem.
متن کاملDimension-eight operators in the weak OPE
We argue that there is a potential flaw in the standard treatment of weak decay amplitudes, including that of ′/ . We show that (contrary to conventional wisdom) dimension-eight operators do contribute to weak amplitudes, at order GF αs and without 1/M2 W suppression. We demonstrate the existence of these operators through the use of a simple weak hamiltonian. Their contribution appears in diff...
متن کاملCocompact Subgroups of Semisimple Lie Groups
Lattices and parabolic subgroups are the obvious examples of cocompact subgroups of a connected, semisimple Lie group with finite center. We use an argument of C. C. Moore to show that every cocompact subgroup is, roughly speaking, a combination of these. We study a cocompact subgroup H of a connected, semisimple Lie group G with finite center. The case where H is discrete is very important and...
متن کاملOn Torsion Subgroups of Lie Groups
We are concerned with torsion subgroups of Lie groups. We extend the classical result of C. Jordan on the structure of finite linear groups to torsion subgroups of connected Lie groups. 1. In [1], Boothby and Wang proved that, for any connected Lie group G, there exists a number k{G) such that any finite subgroup contains an abelian normal subgroup whose index is bounded by k{G), thereby genera...
