Abstract

LHCb provides unique opportunities to study WW and ZZ boson production at forward rapidities at the LHC. It has recently been suggested that a measurement of the WW boson mass by LHCb would complement measurements by ATLAS and CMS. All measurements of the WW mass at hadron colliders are subject to PDF uncertainties, but there would be a partial cancellation of the overall PDF uncertainty when the LHCb result is included in an average with measurements by ATLAS and CMS. Here we review measurements of WW and ZZ boson production by LHCb, and report on a new study of the PDF uncertainty on the LHCb measurement of the WW mass. The latter study includes the proposal of a new approach that should reduce the PDF uncertainty by roughly a factor of two with LHCb Run 2 data.
