NONRELATIVISTIC QUARK–ANTIQUARK POTENTIAL: SPECTROSCOPY OF HEAVY-QUARKONIA AND EXOTIC SUSY QUARKONIA
Abstract
The experiments at LHC have shown that the SUSY (exotic) bound states are likely to form bound states in an entirely similar fashion as ordinary quarks form bound states, i.e. quarkonium. Also, the interaction between two squarks is due to gluon exchange which is found to be very similar to that interaction between two ordinary quarks. This motivates us to solve the Schrödinger equation with a strictly phenomenological static quark–antiquark potential: 
using the shifted large N-expansion method to calculate the low-lying spectrum of a heavy quark with antisbottom 
and sbottom with antisbottom 
bound states with 
is set free. To have a full knowledge on spectrum, we also give the result for a heavier as well as for lighter sbottom masses. As a test for the reliability of these calculations, we fix the parameters of this potential by fitting the spin-triplet (n3S1) and center-of-gravity l≠0 experimental spectrum of the ordinary heavy quarkonia 
, 
and 
to few MeV. Our results are compared with other models to gauge the reliability of these predictions and point out differences.
