[institut] [phys4phys] Group for Gravitation, Particle and Fields seminar, Friday, 26 April 2024

Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Friday, 26 April 2024, at 
11:00 at the Institute of Physics Belgrade, lecture hall 360.

The talk entitled

What about quarkonia in the (non)commutative space?

will be given by Benedek Bukor (The Faculty of Mathematics, Physics and 
Informatics, Comenius University in Bratislava).

Abstract: Quarkonium bound states are especially promising candidates to 
test the probable quantum structure of space-time since they represent a 
system with a reasonably small characteristic distance.
Although the theory of quarkonia is quantum chromodynamics, the 
interaction between the quarks can be heuristically described by the 
quantum mechanical Cornell potential as well.
Firstly, we investigate the quarkonium system in the 3-dimensional 
smooth configuration space. Thereafter, we insert it into a 
non-commutative 3-dimensional configuration space, which is composed of 
concentric fuzzy spheres of increasing radius, called the fuzzy onion, 
in order to extract some consequences of the non-trivial structure of 
the space by means of the quarks' properties.
