25 Dec 2012 | | Abstract: | We present the quarkonia correlators for charmonium and bottomonium systems
in the pseudoscalar, vector and scalar channels. For the description of
quark-antiquark interaction we adopt the temperature dependant colour screening
potential of the power law form. The spectroscopic parameters defined from the
model are employed in the spectral functions to compute the quarkonia
correlators. We find considerable medium modifications to the effective masses
of the quarkonia as well as in the behaviour of the respective radial wave
functions. These modifications are then reflected in the computed correlators.
The general behaviour of correlators in the vector and scalar channel are in
accordance with the latest lattice results while their behaviour in the
pseudoscalar channels are found to be different. | | Source: | arXiv, 1212.5995 | | Services: | Forum | Review | PDF | Favorites | |
