1-loop matching of a thermal Lorentz force

چکیده

A bstract Studying the diffusion and kinetic equilibration of heavy quarks within a hot QCD medium profits from knowledge coloured Lorentz force that acts on them. Starting spatial components vector current, carrying out two matching computations, one for quark mass scale ( M ) another thermal scales $$ \left(\sqrt{MT},T\right) MT T , we determine 1-loop coefficients electric magnetic parts force. The part has non-zero anomalous dimension, which agrees with extracted other considerations, in vacuum. coefficient could enable lattice study colour-magnetic 2-point correlator.

Gravitational Lorentz Force

In quantum gauge theory of gravity, the gravitational field is represented by gravitational gauge field. The field strength of gravitational gauge field has both gravitoelectric component and gravitomagnetic component. In classical level, gauge theory of gravity gives out classical Newtonian gravitational interactions in a relativistic form. Besides, it gives out gravitational Lorentz force whi...

Thermal and Lorentz Force Analysis of Beryllium Windows for a Rectilinear Muon Cooling Channel

Reduction of the 6-dimensional phase-space of a muon beam by several orders of magnitude is a key requirement for a Muon Collider. Recently, a 12-stage rectilinear ionization cooling channel has been proposed to achieve that goal. The channel consists of a series of low frequency (325 MHz-650 MHz) normal conducting pillbox cavities, which are enclosed with thin beryllium windows (foils) to incr...
