Description
We study bottomonium and B mesons at non-zero temperature, using lattice NRQCD for bottom quarks and an ${\cal O} (a)$ improved Wilson action for $N_f = 2+1$ flavors of light quarks on anisotropic lattices. We consider two sets of FASTSUM ensembles, with an anisotropy of $\xi = 3.45$ for the B meson study and $\xi = 7.02$ for the bottomonium study. The pion mass is approximately the same, $m_\pi \sim 380$ MeV. Temperature is varied by changing the number of lattice sites along the time direction, allowing us to examine the spectral properties of these channels in detail. Here, we report on the current status of our studies.
