Top production at the LHC: The impact of PDF uncertainties and correlations
In this contribution we discuss the impact of PDF uncertainties on tt̄ and t-channel single-top production at the LHC. We present predictions for total cross-sections computed at NLO accuracy with different PDF sets. For singletop production, we point out that the uncertainty arising from the choice...

description | In this contribution we discuss the impact of PDF uncertainties on tt̄ and t-channel single-top production at the LHC. We present predictions for total cross-sections computed at NLO accuracy with different PDF sets. For singletop production, we point out that the uncertainty arising from the choice of the bottom quark mass is one of the dominant theoretical uncertainties on the total cross-section. Finally, the possibility of using PDF-induced correlations between top quark and electroweak vector boson production cross-sections to improve the accuracy of LHC measurements is investigated. © Società Italiana di Fisica. |
