QCD_2: 't Hooft equation vs. relativistic Schroedinger equation
Andrei Smilga
We discuss 2-dimensional with a fundamental quark of mass in the 't Hooft limit ( const). The spectrum of this theory includes a ch…
Meson states in `t Hooft model: Hamiltonian approach
A. V. Smilga
We point out that the masses of the highly excited bound quark-antiquark states in QCD in the infinite limit may be determined in the framework of a simple quantum-mechanic…
QCD sum rules: Borel parameter vs. Euclidean time
A. V. Smilga
We explore a modification of QCD sum rules where, instead of Borel transforms of current correlators, one considers the correlators in coordinate space as functions of Euclidean ti…
Symmetries of massless QCD
A. V. Smilga
We present a pedagogical review of certain exact theoretical results concerning the physics of an imaginary world where one quark or more are deprived of their masses.
