The final state is one muon and two or three jets. A Bayesian neural network technique, used to discriminate between the signal and backgrounds. The 95% confidence level (CL) exclusion limits on anomalous right-handed vector, and left- and right-handed tensor Wtb couplings are measured to be $|f_{RV}| < 0.16$, $|f_{LT}| < 0.057$, and $-0.049 < f_{RT} < 0.048$, respectively. For the FCNC couplings $\\kappa_{tug}$ and $\\kappa_{tcg}$, the 95% CL upper limits on coupling strengths are $|\\kappa_{tug}|/\\Lambda < 4.1 \\times 10^{-3} TeV^{-1}$ and $|\\kappa_{tcg}|/\\Lambda < 1.8 \\times 10^{-2} TeV^{-1}$, where $\\Lambda$ is the scale for new physics, and correspond to upper limits on the branching fractions of $2.0 \\times 10^{-5}$ and $4.1 \\times 10^{-4}$ for the decays $t \\rightarrow ug$ and $t \\rightarrow cg$, respectively.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.77022.v1/t1","@type":"Dataset","description":"Predicted and observed event yields before and after multijet BNN selection for $\\sqrt{s}=7$ and $8$ TeV.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.77022.v1/t2","@type":"Dataset","description":"List of input variables for the Bayesian neural networks used in the analysis.
