Recent results from the LHC have focused renewed attention on the determination of the strange-quark parton distribution function (PDF) and the DIS charm process provides important complementary constraints on this quantity. [...] Restricted: PDF PDF (PDFA); 2019-07-0414:47 [PUBDB-2019-02651] Preprint/Report et al 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$^{-1}$.

The data sample corresponds to an integrated luminosity of 35.9 fb$^{−1}$ collected with the CMS detector [...] OpenAccess: PDF PDF (PDFA); 2019-07-0414:41 [PUBDB-2019-02649] Book/Report/Dissertation / PhD Thesis Zagermann, M. On accelerated expansion in string theory [DESY-THESIS-2019-012] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 211 pp. (2019) [10.3204/PUBDB-2019-02649] = Dissertation, Universität Hamburg, 2019   In the first part of this thesis we investigate the viability of a class of models for de Sitter (dS) vacua in string theory, due to Kachru, Kallosh, Linde and Trivedi (KKLT). We start by explaining why the success or failure of such models is sensitive to a large number of Planck suppressed operators, and collect circumstantial evidence that this UV sensitivity cannot be evaded with delicately engineered models such as the Kallosh-Linde (KL) racetrack due to a generic conflict with the weak gravity conjecture (WGC) for axions.

In this search, it is assumed that the H$^+$ boson is produced in decays of top quarks, and the A boson decays to two oppositely charged muons.

The pseudorapidity range of the CMS tracker from $-$2.4 to 2.4 is divided into either two, three, or four distinct subevent regions.

The search is based on proton-proton collisions events collected at 13 TeV by the CMS detector at the CERN LHC.

The analysis uses data from proton-proton collisions at $\sqrt{s}=$ 13 TeV, collected with the CMS detector at the LHC in 2017 and corresponding to an integrated luminosity of 37.5 fb$^{-1}$.
