Underlying Event Tunes and Double Parton Scattering

Using the ``Rivet'' and ``Professor'' framework, we construct a new PYTHIA 6 tune using the CTEQ6L1 PDF and two new PYTHIA 8 UE tunes (one using CTEQ6L1 and one using the HERAPDF1.5LO). By simultaneously fitting CDF data from $\bar{p}p$ collisions at 300 GeV, 900 GeV, and 1.96 Te...

description Using the ``Rivet'' and ``Professor'' framework, we construct a new PYTHIA 6 tune using the CTEQ6L1 PDF and two new PYTHIA 8 UE tunes (one using CTEQ6L1 and one using the HERAPDF1.5LO). By simultaneously fitting CDF data from $\bar{p}p$ collisions at 300 GeV, 900 GeV, and 1.96 TeV together with CMS data for $pp$ collisions at 7 TeV, we test the Underlying Event (UE) models and constrain their parameters, allowing for more precise predictions at 13 TeV and 14 TeV. The consistency of these new tunes with measurements of double-parton scattering (DPS) is also investigated.
