title: "\(|\Delta\phi(W, jb)|\) prefit" of "Measurement of $t$-channel production of single top quarks and antiquarks in $pp$ collisions at 13 TeV using the full ATLAS Run 2 data sample"

description: Pre-fit distribution of the difference in azimuth angle between the reconstructed W boson and the jet pair, \(|\Delta\phi(W, jb)|\), in SR plus.
description: - CERN-LHC. The production of single top quarks and top antiquarks via the $t$-channel exchange of a
virtual $W$ boson are measured in proton--proton collisions at a centre-of-mass energy
of 13 TeV at the LHC. The full Run 2 dataset recorded with the ATLAS detector in the years 2015--2018 is used.
The total cross-sections are determined to be $\sigma(tq)=137^{+8}_{-8}\,\mathrm{pb}$
and $\sigma(\bar{t}q)=84^{+6}_{-5}\,\mathrm{pb}$ for top-quark and top-antiquark production,
respectively.
The combined cross-section is found to be $\sigma(tq+\bar{t}q)=221^{+13}_{-13}\,\mathrm{pb}$ and the
cross-section ratio is $R_{t}=\sigma(tq)/\sigma(\bar{t}q)=1.636^{+0.036}_{-0.034}$.
The measured cross-sections are in good agreement with predictions made at
next-to-next-to-leading order in quantum chromodynamics.
The predicted value of $R_{t}$ using different sets of parton
distribution functions is compared to the measured value, demonstrating the potential to further 
constrain the functions when using this result in global fits.
The measurements of $\sigma(tq)$, $\sigma(\bar{t}q)$, and $\sigma(tq+\bar{t}q)$ are interpreted in an effective field
theory approach, setting limits at the 95\% confidence level on the strength of a four-quark operator
and an operator coupling the third quark generation to the Higgs boson doublet:
$-0.37 &lt; C_{qQ}^{(1,3)}/\Lambda^2 &lt; 0.06$ and
$-0.87 &lt; C_{\phi Q}^{(3)}/\Lambda^2 &lt; 1.42$.
The measured total cross-section is further used to derive the constraint $|V_{tb}|&gt;0.95$ at the 95%
confidence level.
In a more general approach, pairs of CKM matrix elements involving top quarks are simultaneously
constrained, leading to confidence contours in the corresponding two-dimensional
parameter spaces.

description: Summary of inclusive cross section.
description: First measurements of the opposite-sign W boson pair production cross section in proton-proton collisions at sqrt(s) = 13.6 TeV are presented. The data used in this study were collected collisions at sqrt(s) = 13 TeV is presented. The data used in this study were collected with with the CMS detector at the CERN LHC in 2022, and correspond to an integrated luminosity of 34.8 fb-1. Events are selected by requiring one electron and one muon of opposite charges. A maximum likelihood fit leptons (electrons or muons). Two methods for reducing background contributions is performed in event categories defined by the flavour and charge of the leptons, the number of jets, and number of jets identified as originating from b quarks. An inclusive WW production cross section of 125.7 +/- 5.6 pb is measured, in agreement with standard model predictions. Cross sections are also reported in a fiducial region close to that of the detector acceptance, both inclusively and differentially as a function of the jet multiplicity in the event.

description: Measurements at sqrt(s)= 13.6 TeV of the opposite-sign W boson pair production cross section in proton-proton collisions are presented. The data used in this study were collected with the CMS detector at the CERN LHC in 2022, and correspond to an integrated luminosity of 34.8 fb-1. Events are selected by requiring one electron and one muon of opposite charge. A maximum likelihood fit is performed on signal- and background-enriched data categories defined by the flavour and charge of the leptons, the number of jets, and number of jets originating from b quarks. The overall sensitivity is significantly better than previous results with a similar integrated luminosity. The improvement comes from a more refined control of experimental uncertainties and an improved fit strategy. An inclusive WW production cross section of 125.7 +/- 5.6 pb is measured, in agreement with standard model predictions. Cross sections are also reported in a fiducial region close to that of the detector acceptance, both inclusively and differentially, as a function of the jet multiplicity in the event. For the first time in proton-proton collisions, WW events with zero, one, and at least two jets are studied simultaneously and compared with recent theoretical predictions.
