Twisted mass QCD for weak matrix elements
I report on the application of tmQCD techniques to the computation of hadronic matrix elements of four-fermion operators. Emphasis is put on the computation of B K in quenched QCD performed by the ALPHA Collaboration. The extension of tmQCD strategies to the study of neutral B-meson mixing is briefly discussed. Finally, some remarks are made concerning proposals to apply tmQCD to the computatio...
متن کاملImproved Formulation of Global QCD Analysis with Zero-mass Matrix Elements
The zero-mass (ZM) parton formalism is widely used in high-energy physics because of its simplicity and historical importance, even while massive quarks (c, b, t) are playing an increasingly prominent role in particle phenomenology, including global QCD analyses of parton distributions based on the more precise general-mass (GM) QCD formalism. In view of this dichotomy, we show how the obvious ...
متن کاملA symmetric boundary integral formulation for cohesive interface problems
An incremental symmetric boundary integral formulation for the problem of many domains connected by non-linear cohesive interfaces is here presented. The problem of domains with traction-free cracks and/or rigid connections are particular instances of the proposed cohesive formulation. The numerical approximation of the considered problem is achieved by the symmetric Galerkin boundary element m...
متن کاملMatrix formulation of the surface-enhanced Raman optical activity theory.
The previously formulated surface-enhanced SE Raman optical activity ROA theory is based on a multipole electromagnetic field expansion. The field of molecule and colloid particles is induced by the excitation light. Although this semistatic polarization is not the only enhancement mechanism, it provides a good basis for understanding of the phenomenon. However, the mathematical expressions bec...
متن کاملParallel Simulations of Dynamic Fracture Using Extrinsic Cohesive Elements
In this paper, we present a novel parallel implementation of extrinsic initially rigid cohesive elements in an explicit finite element solver designed for the simulation of dynamic fracture events. The implementation is based on activating instead of inserting the cohesive elements and uses ParFUM, a parallel framework specifically developed for simulations involving unstructured meshes. Aspect...
