Extraction and validation of a new set of CMS pythia8 tunes from underlying-event measurements

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

New sets of CMS underlying-event parameters ("tunes") are presented for the pythia8 event generator. These tunes use the NNPDF3.1 parton distribution functions (PDFs) at leading (LO), next-to-leading (NLO), or next-to-next-to-leading (NNLO) orders in perturbative quantum chromodynamics, and the strong coupling evolution at …

Constraints on anomalous HVV couplings from the production of Higgs bosons decaying to τ lepton pairs

A. M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres

A study is presented of anomalous $HVV$ interactions of the Higgs boson, including its $CP$ properties. The study uses Higgs boson candidates produced mainly in vector boson fusion and gluon fusion that subsequently decay to a pair of $\ensuremath{\tau}$ leptons. The data …
