An Update of the ABMP16 PDF Fit
[arXiv:1909.03533; DESY-19-152; DO-TH 19/16; SAGEX-19-21]
XXVII international workshop on deep-inelastic scattering and related subjects, DIS2019, TorinoTorino, Italy, 8 Apr 2019 - 12 Apr 20192019-04-082019-04-12 Proceedings of Science / International School for Advanced Studies (DIS2019), 002 () [10.3204/PUBDB-2019-03343]  GO
We present an updated version of the ABMP16 nucleon PDFs, which is tuned by using recent precise data on $W$- and $Z/\gamma^*$-production at the LHC and the final HERA data on DIS $c$- and $b$-quark production and by imposing a stringent $Q^2$-cut on the inclusive DIS data in order to avoid the impact of higher twist terms at small $x$ at HERA. The new $W$- and $Z$-boson production data, in particular the updated version of the ATLAS data at the c.m.s. [...]

Overview of HERMES results
XVIII Workshop on High Energy Spin Physics, DSPIN-19, DubnaDubna, Russia, 2 Sep 2019 - 6 Sep 20192019-09-022019-09-06  GO
The HERMES experiment has collected a wealth of data using the 27.6 GeV polarized HERA lepton beam and various polarized and unpolarized gaseous targets. This allows for a series of unique measurements of observables sensitive to the multidimensional (spin) structure of the nucleon, in particular semi-inclusive deep-inelastic scattering (SIDIS) measurements, for which the HERMES dual-radiator ring-imaging Cherenkov counter provided final-hadron identification between 2 GeV to 15 GeV for pions, kaons, and (anti)protons.

Search for the production of W$^\pm$W$^\pm$W$^\mp$ events at $\sqrt{s} =$ 13 TeV
[arXiv:1905.04246; CMS-SMP-17-013; CERN-EP-2019-074]
A search for the production of events containing three W bosons predicted by the standard model is reported. The search is based on a data sample of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the CMS experiment at the CERN LHC and corresponding to a total integrated luminosity of 35.9 fb$^{-1}$.

Search for supersymmetry with a compressed mass spectrum in the vector boson fusion topology with 1-lepton and 0-lepton final states in proton-proton collisions at $\sqrt{s}=$ 13 TeV
[arXiv:1905.13059; CMS-SUS-17-007; CERN-EP-2019-093]
A search for supersymmetric particles produced in the vector boson fusion topology in proton-proton collisions is presented. The search targets final states with one or zero leptons, large missing transverse momentum, and two jets with a large separation in rapidity. [...]

Confronting EFT with artificial neural networks in the quest for physics beyondthe Standard Model - Probing new paths for measuring dimension-6 operators in top-quark physics at LHC
Hamburg : University of Hamburg 64 pp. () [10.3204/PUBDB-2019-03421] = Masterarbeit, University of Hamburg, 2019  GO
As no sign of physics beyond the Standard Model has emerged at the Large Hadron Collider sofar, high precision measurements of particle properties and couplings become increasingly interesting.A commonly used language to interpret these measurements is effective field theory, inwhich higher-dimensional operators are added to the Standard Model. Traditional approachesmost commonly set constraints on anomalous couplings by employing and combining unfoldedmeasurements. [...]

[arXiv:1906.06441; CMS-EXO-19-001; CERN-EP-2019-113]
A search for long-lived particles decaying to displaced, nonprompt jets and missing transverse momentum is presented. The data sample corresponds to an integrated luminosity of 137 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC in 2016-2018.
