Hello, For the analysis I'm doing, which is ttbar in the l+jets channel to look for four-fermion operators, a major background is single top. Do these backgrounds exist for the LHC 13 or 14 somewhere? I haven't been able to find them on any of the pages linked to from the twiki. Thank you. m ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the SNOWMASS-TOP list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=SNOWMASS-TOP&A=1
