Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 31.10 будут заслушаны 2 доклада:
11:30 Олег Андреев
Несколько комментариев о тяжёлых тетракварках

I will make a few comments on heavy tetraquarks using the gauge/string duality. In particular, I describe the structure of the two low-lying Born-Oppenheimer potentials.

12:30 Ю. Н. Обухов (ИБРАЭ РАН)
Spin dynamics of fermions in external fields

This talk presents results of a comprehensive study of the classical and
quantum dynamics of spin 1/2 Dirac fermion particles with dipole moments
under the action of arbitrary external fields (including gravitational,
inertial, electromagnetic, axion ones). The gauge-theoretic framework of
the general-relativistically covariant Dirac theory is used to describe
in a consistent way the minimal and nonminimal couplings of fermions to
external fields of different physical nature. The quantum and
quasiclassical equations of motion are derived and a complete consistency
of the quantum and classical spin dynamics is demonstrated. Applications
range from astrophysics, to precision experiments with polarized particles
in accelerators and storage rings, to the heavy-ion collisions.
