B Physics from lattice QCD

Obiettivo

Precision tests of the Standard model of particle physics are focussed on the weak interaction decays of quarks inside B mesons in the hope of finding an internal inconsistency, which will point to a deeper theory. Such studies need theoretical input in the form of calculated decay matrix elements for B mesons in QuantumChromodynamics (QCD), since the binding by the strong force of the b quark inside the B meson is critical. The matrix elements must be calculated fully non-perturbatively using the numerical techniques of lattice QCD, and this is a very challenging problem. This project aims to perform such a calculation of one of the key matrix elements needed by experiment: that of neutral B mixing. The calculation will use a new 5 Flops supercomputer in the UK and a number of new techniques to enable a much more accurate result to be obtained than before. In particular we will be able to include dynamical u and d quarks in the vacuum with very light masses for the first time. Non-relativistic techniques developed in Glasgow will be used for the heavy b quark. The generation of the gluon field configurations will be done by the UKQCD collaboration, of which Glasgow is a key part. The research provides a solid training in all aspects of lattice QCD; theoretical formalism, supercomputing and particle physics phenomenology, not available to the researcher at her home institution. The scientist in charge has an established international reputation in this area and has had much success in mentoring younger women physicists to achieve their goals. The project will broaden the experience of the researcher into new areas allowing her to develop a promising career path as an independent researcher, which will benefit her home region on her return. A new link will be developed between the UK and Spain, strengthening the European Research Area in a high profile field.
