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 ...

Weyl-invariant Einstein-Cartan gravity: unifying the strong CP and hierarchy puzzles

Mikhail Chapochnikov

We show that the minimal Weyl-invariant Einstein-Cartan gravity in combination with the Standard Model of particle physics contains just one extra scalar degree of freedom (in addition to the graviton and the Standard Model fields) with the properties of a ...

Search for Leptonic Decays of Dark Photons at NA62

Radoslav Marchevski, Alina Kleimenova

The NA62 experiment at CERN, configured in beam-dump mode, has searched for dark photon decays in flight to electron-positron pairs using a sample of 1.4 x 10(17) protons on dump collected in 2021. No evidence for a dark photon signal is observed. The comb ...

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 ...

Evidence on the effects of main-chamber neutrals on density shoulder broadening

Basil Duval, Nicola Vianello, Holger Reimerdes, Christian Gabriel Theiler, Umar Sheikh, Cedric Kar-Wai Tsui, Mirko Wensing, Marcelo Baquero Ruiz, Artur Perek, Sophie Danielle Angelica Gorno

Evidence that density shoulder broadening is dependent on high main-chamber neutral density is presented. Shoulder broadening does notoccur when the sources for main-chamber neutrals are minimized using divertor baffles and wide gaps to the first wall (sim ...

Measurement of the cross section for tt¯ production with additional jets and b jets in pp collisions at s√ = 13 TeV

Lesya Shchutska

Measurements of the cross section for the production of top quark pairs in association with a pair of jets from bottom quarks and in association with a pair of jets from quarks of any flavor or gluons and their ratio are presented. The data were collected ...
