Bottomonia correlators and spectral functions at zero and finite temperature
Abstract
We present preliminary studies of bottomonia spectral functions at zero and finite temperature using quenched anisotropic lattices. The heavy quark is treated within Fermilab approach. We find no modification of the $η_b$ and $Υ$ states up to temperatures $2.3T_c$ while our study suggest dissolution of $χ_b$ state at $1.15T_c$.
