The two-loop coefficient functions for double deeply virtual Compton scattering

Vladimir M. Braun, Hua-Yu Jiang, Alexander N. Manashov +1

Making use of conformal symmetry of large- $n_{f}$ QCD in $d = 4 - 2 I^µ$ dimensions at the Wilson-Fischer fixed point, we calculate the two-loop coefficient functions in the operator produ…

An improved calculation of the $D_{(s)}^{} D_{(s)} V$ and $B_{(s)}^{} B_{(s)} V$ couplings from light-cone sum rules

Su-Ping Jin, Hua-Yu Jiang

We present an improved calculation of the $D_{(s)}^{*} D_{(s)} V$ and $B_{(s)}^{*} B_{(s)} V$ coupling constants, where $V$ denotes $I ¨ $ , $K^{*}$ , $I ¨ $ , and $I ¨ $ meson. These couplings go…

Precision calculations of the $D_{(s)} D_{(s)} V$ and $B_{(s)} B_{(s)} V$ couplings from light-cone sum rules

Hua-Yu Jiang, Su-Ping Jin

We present an improved calculation of the $H H V$ ( $H = D_{(s)}, B_{(s)}$ , $V = I ¨ $ , $K^{*}$ , $I ¨ $ , and $I ¨ $ ) coupling constants $g_{H H V}$ beyond leading order in $I^\pm_{s}$ from QCD lig…
