We study $J/\ensuremath{\psi}$ and ${\ensuremath{\eta}}_{c}$ inclusive production in $\mathrm{\ensuremath{\Upsilon}}$ decay within the framework of nonrelativistic-QCD (NRQCD) factorization. In the latter case, for which no experimental data exist so

A novel Bi2S3 microsphere was fabricated through one-pot urea-assisted solvothermal method. The synthesized Bi2S3 microsphere was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transformed infrared spectroscopy

To understand the $J/\ensuremath{\psi}+{X}_{\mathrm{non}\text{\ensuremath{-}}c\overline{c}}$ production mechanism in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation, in this work, we propose to measure the cross section for $J/\ensuremath{\psi}$ productio

In this paper, we give a brief review of recent theoretical studies of double prompt [Formula: see text] production at the FNAL Tevatron and the CERN LHC, to which both single- and double-parton-scattering processes contribute. In single parton scatt

We study double prompt $J/\psi$ hadroproduction within the nonrelativistic-QCD factorization formalism adopting the parton Reggeization approach to treat initial-state radiation in a gauge invariant and infrared-safe way. We present first predictions

Based on the hypothesis that the $X(3872)$ exotic hadron is a mixture of ${\ensuremath{\chi}}_{c1}(2P)$ and other states and that its prompt hadroproduction predominately proceeds via its ${\ensuremath{\chi}}_{c1}(2P)$ component, we calculate the $\m

We study inclusive processes involving two heavy quarkonia in nonrelativistic QCD (NRQCD) and demonstrate that, in the presence of two P-wave Fock states, NRQCD factorization breaks down, leaving uncanceled infrared singularities. As phenomenological

Inclusive $\chi_{cJ}$ $(J=0,1,2)$ production from $\Upsilon(1S)$ decay is studied within the framework of nonrelativistic QCD (NRQCD) factorization at leading order in $v_Q^2$, which includes the contributions of $b\bar{b}({}^3S_1^{[1]})\to c\bar{c}(

We report on our analysis [1] of prompt ηc meson production, measured by the LHCb Collaboration at the Large Hadron Collider, within the framework of non-relativistic QCD (NRQCD) factorization up to the sub-leading order in both the QCD coupling con
