Description
We present an extraction of the MSbar mass of bottom quark from the Upsilon(1S) system. We account for the leading renormalon effects in the extraction. We work in the renormalon subtracted scheme in order to control the divergence of the perturbation series coming from the pole mass renormalon, and we carefully take into account the charm quark effects.
