Renormalization of infrared contributions to the QCD pressure
نویسندگان
چکیده
Thanks to dimensional reduction, the infrared contributions to the QCD pressure can be obtained from two different three-dimensional effective field theories, called the Electrostatic QCD (YangMills plus adjoint Higgs) and the Magnetostatic QCD (pure Yang-Mills theory). Lattice measurements have been carried out within these theories, but a proper interpretation of the results requires renormalization, and in some cases also improvement, i.e. the removal of terms of O(a) or O(a2). We discuss how these computations can be implemented and carried out up to 4-loop level with the help of Numerical Stochastic Perturbation Theory.

متن کاملInfrared Divergences and Non-lightlike Eikonal Lines in Sudakov Processes Typeset Using Revt E X 1
We propose a method to analyze infrared contributions to non-inclusive processes in QCD. We use the one-loop Sudakov form factor as a working example. Borrowing techniques from renormalization theory, we construct coun-terterms for the contributions from the soft and collinear regions, and we relate them to eikonal Wilson lines taken along non-lightlike directions.
متن کاملInfrared divergences and non - lightlike eikonal lines in Sudakov processes
We propose a method to analyze infrared contributions to non-inclusive processes in QCD. We use the Sudakov form factor as a working example. Borrowing techniques from renormalization theory, we construct “counterterms” for the contributions from the soft and collinear regions, and we relate them to eikonal Wilson lines taken along non-lightlike directions. We illustrate the method with explici...
متن کاملThe role of electroweak penguin and magnetic dipole QCD penguin on hadronic b Quark Decays
This research, works with the effective Hamiltonian and the quark model. Using, the decay rates of matter-antimatter of b quark was investigated. We described the effective Hamiltonian theory which was applied to the calculation of current-current (Q1,2), QCD penguin (Q3,…,6), magnetic dipole (Q8) and electroweak penguin (Q7,…,10) decay rates. The gluonic penguin structure of hadronic decays ...
متن کاملMeasuring infrared contributions to the QCD pressure
For the pressure (or free energy) of QCD, four-dimensional (4d) lattice data is available at zero baryon density up to a few times the critical temperature Tc. Perturbation theory, on the other hand, has serious convergence problems even at very high temperatures. In a combined analytical and three-dimensional (3d) lattice method, we show that it is possible to compute the QCD pressure from abo...
