Title: $n / s - \hat{q} / T^{3}$ relation at next-to-leading order in QCD

Abstract

The relation between the specific shear viscosity $η/s$ and the dimensionless jet quenching parameter $$\hat{q}$$/$$T^3$ in perturbative QCD is explored at next-to-leading order in the coupling constant. It is shown that the relation changes little, although both transport coefficients independently are subject to large modifications at the next-to-leading order level. This finding confirms that the relationship is robust.

Journal Article Kato, Y. ; Iijima, T. ; Adachi, I. ; ... - Physical Review D

We present the measurement of the absolute branching fractions of B⁺ → X_cc¯K⁺ and B⁺ → D¯^(*)0π₊ decays, using a data sample of 772 × 10⁶ BB¯ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e⁺e^– collider. Here, X_cc¯ denotes η_c, J/ψ, χ_c0, χ_c1, η_c(2S), ψ(2S), ψ(3770), X(3872), and X(3915). We do not observe significant signals for X(3872) or X(3915) and set the 90% confidence level upper limits at B(B⁺ → X(3872)K⁺) < 2.6 × 10^–4and B(B⁺ → X(3915)K⁺) < 2.8 × 10^–4. These represent the most stringent upper limit for B(B⁺ → X(3872)K⁺)more »« less

We study η_c production at center-of-mass energies √s from 4.18 to 4.60 GeV in e⁺e^– annihilation data collected with the BESIII detector operating at the BEPCII storage ring, corresponding to 7.3 fb^–1 of integrated luminosity. We measure the cross sections of the three different exclusive reactions e⁺e^– → η_cπ⁺π^–π⁰, e⁺e^– → η_cπ⁺π^–, and e⁺e^– → η_cπ⁰γ. We find significant η_c production in e⁺e^– → η_cπ⁺π^–π⁰ at √s of 4.23 GeV and 4.26 GeV and observe a significant energy-dependent Born cross section that we measure to be consistent with the production via the intermediate Y(4260) resonance. In addition, we perform a search for a charmoniumlike Z_c state close to themore »« less
