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 $\eta_b$ and $\Upsilon$ states up to temperatures $2.3T_c$ while our study suggest dissolution of $\chi_b$ state at $1.15T_c$ .
