Scale-invariant total decay width $Γ (H \to b b ˉ)$ using the novel method of characteristic operator

Jiang Yan, Xing-Gang Wu, Jian-Ming Shen +2

In this paper, a novel method via using the characteristic operator~(CO) $D^_{n_{γ}, n_{β}}$ is proposed to extend the applicability of PMC, which is a theoretical generali…

Improved analysis of the decay width of $t \to W b$ up to N $^{3}$ LO QCD corrections

Jiang Yan, Xing-Gang Wu, Hua Zhou +2

In this paper, we analyze the top-quark decay $t \to W b$ up to next-to-next-to-next-to-leading order (N $^{3}$ LO) QCD corrections. For the purpose, we first adopt the principle of ma…

Improved analysis of double $J / ψ$ production in $Z$ -boson decay

Guang-Yu Wang, Xing-Gang Wu, Xu-Chang Zheng +2

In this paper, we present an improved calculation for the decay rate of the rare $Z$ -boson decay into $J / ψ + J / ψ$ . This decay is dominated by the photon fragmentation mechanism, i.e…
