Description

This workshop will take place at IPPP Durham from Tuesday 2nd of April morning to Friday 5th of April lunch-time. The whole day Tuesday will be devoted to a discussion of pTW/Z predictions (MC in the morning, resummation calculations in the afternoon). The Wednesday morning will be devoted to QED/EW corrections related to DY production at the LHC. The Thursday morning will be devoted to experimental progress, combinations, electroweak fits, etc, while Thursday afternoon will be devoted to PDFs. Finally, Friday morning will be open for other topics and further discussion which could not take place earlier in the week on some of the relevant topics if needed.
