[dgocanin]

Zdravo svima,

najavljujem da će u petak, 26. aprila, Benedek Bukor (The Faculty of 
Mathematics, Physics and Informatics, Comenius University in Bratislava) 
održati seminar na Institutu za fiziku.

Naslov: What about quarkonia in the (non)commutative space?

Apstrakt: 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.

spratu. Osim toga, seminar se može pratiti i preko linka
