Correlator of heavy-light quark currents in HQET in the large limit
Andrey G. Grozin
The perturbative contribution to the correlator of two heavy-light quark currents in HQET expanded in light-quark masses up to quadratic terms is calculated at the leading order in…
Correlators of heavy-light quark currents in HQET: Perturbative contribution up to 4 loops and beyond
Andrey G. Grozin
The perturbative contribution to the correlator of two HQET heavy-light currents expanded in light-quark masses up to quadratic terms is calculated up to 4 loops. The leading large…
Drawing Feynman diagrams with GLE
A. G. Grozin
A package for drawing publication-quality Feynman diagrams written in GLE is described.
Effective field theories
Andrey Grozin
A pedagogical introduction to low-energy effective field theories. In some of them, heavy particles are "integrated out" (a typical example - the Heisenberg-Euler EFT); in some hea…
Introduction to effective field theories. 3. Bloch--Nordsieck effective theory, HQET
A. G. Grozin
This is a continuation of the lectures [1,2]. In this part we discuss interaction of electrons with soft photons in QED and Heavy Quark Effective Theory (HQET).
Quantum Chromodynamics
Andrey Grozin
The classical Lagrangian of chromodynamics, its quantization in the perturbation theory framework, and renormalization form the subject of these lectures. Symmetries of the theory…
