Dear colleagues,
You are cordially invited to the Low-Background Laboratory for Nuclear
Physics hybrid (live/online) seminar, which will be held on Monday, 23
May 2022 at 11:00 at the Institute of Physics Library (big hall) and
Zoom (link is given below).
The talk entitled:
Transverse-momentum dependent Distributions: Functional Complexity
manifesting in Gluon Poles and Inverse Radon Transforms
will be given by Prof. Dr Igor Anikin (Bogoliubov Laboratory of
Theoretical Physics, Joint Institute for Nuclear Research (JINR), Dubna,
Russia).
Abstract of the talk:
As well-known, QCD can be applied to the description of hard reactions
with the help of the factorization theorem.
The factorization theorem, as an extended method of asymptotical
estimations, states that the short (hard) and long (soft) distance
dynamics can be separated out provided the momentum transfer is large.
In this connection, any types of parton distributions are stemming from
the factorization procedure applied for a given hard process. In the
talk, we discuss the functional complexity which is associated with the
transverse momentum dependent parton distributions. Working with the
semi-exclusive and inclusive reactions, we demonstrate the manifestation
of complexity in the gluon pole contributions and in the inverse Radon
transforms applied to the transverse momentum dependent generalized
parton distributions. The experimental observables which are directly
probing the gluon poles have been suggested.
Biography:
Prof. Dr Igor V. Anikin is a world-wide recognized expert in the
high-and-low energy theoretical physics. At present Prof. Dr. Igor
Anikin is the Head of the Standard Model Sector in the Joint Institute
for Nuclear Research (JINR) at the Bogoliubov Laboratory of Theoretical
Physics in Dubna (Russia).
His scientific interests are covering the following fields:
(i) High Energy Hadron Physics: spin physics, leading and higher twist
(in the hard scale) contributions for both inclusive and exclusive
processes, different mathematical aspects of factorization theorem (the
renormalization group-structure, direct and inverse Radon
transformations, path group representations, application of conformal
symmetry), generalized parton distributions and their analytical
properties, light-cone sum rules based on the dispersion relations and
duality;
(ii) Nontrivial Topological objects and QCD Vacuum structure: instanton
effects in the low energy theories, quark-hadron interaction modelling
induced by instantons;
(iii) Effective Theories: heavy quark effective theory, effective
theory in the collinear limit taking into account the soft
contributions, quark-hadron effective theories, superflavour symmetry in
the heavy quark effective model.
In the year of 1996, Igor V. Anikin received his PhD degree (the
Candidate of Sciences) in Mathematics and Physics with his thesis titled
as “The light and heavy baryon form factors within the relativistic
quark models” in JINR. In 2014, he defended his Dr.Sc. (Doctor of
Sciences in Physics and Mathematics) dissertation (which is the
equivalent of habilitation thesis in Europe) entitled “The higher twist
contributions in QCD hard processes”.
In April of 2018, by the decision of the Presidium of the Russian
Academy of Sciences, Igor V. Anikin has been awarded by the
distinguished academic title “Professor of the Russian Academy of
Sciences”.
