Charm-Meson -channel Singularities in an Expanding Hadron Gas
Eric Braaten, Roberto Bruschini, Li-Ping He +2
We study the time evolution of the numbers of charm mesons after the kinetic freezeout of the expanding hadron gas produced by the hadronization of the quark-gluon plasma from a ce…
Production of at High Multiplicity
Eric Braaten, Li-Ping He, Kevin Ingles +1
The dependence of the production of the meson on the hadron multiplicity in collisions has been used as evidence against being a charm-meson molecule. The argume…
Galilean-Invariant XEFT at Next-to-Leading Order
Eric Braaten, Li-Ping He, Jun Jiang
XEFT is a low-energy effective field theory for charm mesons and pions that provides a systematically improvable description of the resonance. To simplify calculations be…
Charm-meson Triangle Singularity in Annihilation into
Eric Braaten, Li-Ping He, Kevin Ingles +1
We calculate the cross section for annihilation into at center-of-mass energies near the threshold under the assumption that $X(…
Production and constraints for a massive dark photon at electron-positron colliders
Jun Jiang, Chun-Yuan Li, Shi-Yuan Li +3
Dark sector may couple to the Standard Model via one or more mediator particles. We discuss two types of mediators: the dark photon and the dark scalar mediator . T…
Excited heavy quarkonium production in Higgs boson decays
Qi-Li Liao, Jun Jiang
The rare decay channels of Higgs boson to heavy quarkonium offer vital opportunities to explore the coupling of Higgs to heavy quarks. We study the semi-exclusive decay channels of…
