论文摘要
我们在LHC的背景下对异常$ WTB $相互作用进行了独家研究。 $ WTB $异常耦合的限制是通过测量顶级衰减宽度和横截面以及生产不对称的估计的,以防CP违反CP。我们的调查表明,$(| c_l |,| c_r |)$上的上限约为(1.82,0.03)$ \ times 10^{ - 4} $ at $2.5σ$ c.l.,对于已在LHC上收集到的LHC的数据,$ \ sqrt {s} = 13 $ tev = 13 $ tev = 13 $ tev for $ tev for $ 139 fb $ 139 fb。未来的强子山子山脉孔的相应限制,即高光度LHC(HL-LHC),高能量LHC(HE-LHC)和未来的圆形对撞机(FCC-HH),用于3 ab $^{ - 1} $,12 ab $^$^$^$^$^{ - 1} $和30 ab $^$^$^$^$^$^$^ab^ab $^{ - 1} $^ab^ab^$^$^ab^ab^$^$^$^at 0的相应限制。 10^{ - 4} $,$(0.44,0.0017)\ times 10^{ - 4} $和$(0.21,0.0004)\ times 10^{ - 4} $在2.5 $ c. l ..
We perform an exclusive study of the anomalous $Wtb$ interaction in the context of LHC. The limits on $Wtb$ anomalous couplings have been estimated via the measurements of the top-quark decay width and cross-section as well as production asymmetries in case the CP is violated. Our investigations reveal that the upper bounds on $(|C_L|, |C_R|)$ would be of about (1.82, 0.03) $\times 10^{-4}$ at $2.5 σ$ C.L., for the already collected data at the LHC with $\sqrt{S} = 13$ TeV for an integrated luminosity of 139 fb$^{-1}$. The corresponding limits for future hadron colliders, namely, High Luminosity LHC (HL-LHC), High Energy LHC (HE-LHC) and Future Circular Collider (FCC-hh) for the projected luminosities of 3 ab$^{-1}$, 12 ab$^{-1}$ and 30 ab$^{-1}$ are found to be to $(0.81, 0.006)\times 10^{-4}$, $(0.44, 0.0017)\times 10^{-4}$ and $(0.21, 0.0004)\times 10^{-4}$ respectively at 2.5$σ$ C.
