Keywords: | [No Keyword Available] | Publisher: | Amer Physical Soc | Abstract: | The inclusive cross section for the production of a single top quark in association with a W boson is measured using 140 fb(-1) of proton-proton collision data collected with the ATLAS detector at root s = 13 TeV. Events containing two charged leptons and at least one jet identified as originating from a b-quark are selected. A multivariate discriminant is constructed to separate the tW signal from the t (t) over bar background. The cross section is extracted using a profile likelihood fit to the signal and control regions and it is measured to be sigma(tW) = 75(-14)(+15) pb, in good agreement with the Standard Model prediction. The measured cross section is used to extract a value for the left-handed form factor at the Wtb vertex times the CabibboKobayashi-Maskawa matrix element vertical bar f(LV)V(tb)vertical bar of 0.97 +/- 0.10. | Description: | Aad, Georges/0000-0002-6665-4934; Carbone, Antonio/0000-0002-4117-3800; Petersen, Troels/0000-0003-0221-3037; Nasella, Laura/0000-0002-4871-784X; Fernandez-Martinez, Pablo/0000-0002-7818-6971; Ragusa, Francesco/0000-0002-4064-0489; Kretzschmar, Jan/0000-0002-8515-1355; Ventura, Andrea/0000-0002-3368-3413; Sala, Alessandro/0000-0003-0824-7326; Calafiura, Paolo/0000-0002-1692-1678; Camplani, Alessandra/0000-0002-6386-9788; Gwilliam, Carl/0000-0002-9401-5304; Abbott, Braden/0000-0002-5888-2734; D'Auria, Saverio/0000-0003-3393-6318; Aboulhorma, Asmaa/0000-0002-9987-2292; Abdelhameed, Sara/0000-0002-0287-5869; Carmignani, Joseph (Joe)/0000-0002-1705-1061; Canbay, Ali Can/0000-0003-4602-473X; Stanislaus, Beojan/0000-0001-9007-7658; Abicht, Nils Julius/0000-0001-5763-2760; Mazzeo, Elena/0000-0002-8406-0195; Tian, Yusong/0000-0001-8739-9250; Rompotis, Nikolaos/0000-0003-2577-1875; Abramowicz, Halina/0000-0001-5329-6640 | URI: | https://doi.org/10.1103/PhysRevD.110.072010 | ISSN: | 2470-0010 2470-0029 |
