Simultaneous extraction of top quark mass, strong coupling, effective mixing angle, and proton PDFs using inclusive DIS and proton-proton collision data
Mikel Mendizabal Morentin, Katerina Lipka, Giovanni Limatola +4
We present the first simultaneous determination of the proton parton distribution functions (PDFs) together with the strong coupling, the top quark pole mass, and the effective wea…
Threshold Top-Quark Pair-Production: Cross Sections and Key Uncertainties
Maria Vittoria Garzelli, Giovanni Limatola, Sven-Olaf Moch +2
We study theoretical uncertainties in predicting top-quark pair-production near threshold at the LHC using the non-relativistic QCD framework. We include variations in the top-quar…
Determination of the strong coupling from high-energy data
S. Alekhin, M. V. Garzelli, S. Moch +1
We determine the strong coupling from high-energy data for the Drell-Yan (DY) process and top-quark hadro-production collected at the Large Hadron Collider and the Tevatron combine…
Top-quark pole mass extraction at NNLO accuracy
S. Alekhin, M. V. Garzelli, J. Mazzitelli +2
We describe our recent NNLO QCD extraction of the top-quark pole mass from fits to experimental data on total inclusive and normalized (multi)-differential cross sections for $t\ba…
NNLO fits of top-quark mass using total, single-differential and double-differential cross-section data
S. Alekhin, M. V. Garzelli, J. Mazzitelli +2
We describe the fits of the top-quark mass value at NNLO using as input the double-differential distributions in rapidity and invariant mass of pairs obtained by the ATL…
