Measurement of the T(t)over-barh and Th Production Rates in the H →b(b)over-bar Decay Channel Using Proton-proton Collision Data at √s=13 Tev

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk

An analysis of the production of a Higgs boson (H) in association with a top quark-antiquark pair (t (t) over barH) or a single top quark (tH) is presented. The Higgs boson decay into a bottom quark-antiquark pair (H -> b (b) over bar) is targeted, and thr ...

Test of lepton flavor universality in B± → K± μ+μ- and B± → K± e+ e- decays in proton-proton collisions at √s=13 TeV

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk

A test of lepton flavor universality in B-+/- -> K +/- mu(+) mu(-) and B-+/- -> (K)+/- e(+) e(-) decays, as well as a measurement of differential and integrated branching fractions of a nonresonant B-+/- -> K-+/- mu(+)mu(-) decay are presented. The analysi ...

Search for physics beyond the standard model in top quark production with additional leptons in the context of effective field theory

Jan Steggemann, Konstantin Androsov, Anna Mascellani, Joanna Malgorzata Wanczyk

A search for new physics in top quark production with additional final-state leptons is performed using data collected by the CMS experiment in proton-proton collisions at root s = 13TeV at the LHC during 2016-2018. The data set corresponds to an integrate ...

First Search for Exclusive Diphoton Production at High Mass with Tagged Protons in Proton-Proton Collisions at root s=13 TeV

Jan Steggemann

A search for exclusive two-photon production via photon exchange in proton-proton collisions, pp -> p gamma gamma p with intact protons, is presented. The data correspond to an integrated luminosity of 9.4 fb(-1) collected in 2016 using the CMS and TOTEM d ...
