Production of $X (3872)$ at High Multiplicity

Eric Braaten, Li-Ping He, Kevin Ingles +1

The dependence of the production of the $X (3872)$ meson on the hadron multiplicity in $pp$ collisions has been used as evidence against $X$ 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 $X (3872)$ resonance. To simplify calculations be…

Masses of Doubly Heavy Tetraquarks with Error Bars

Eric Braaten, Li-Ping He, Abhishek Mohapatra

In the heavy-quark limit, the two heavy quarks in a doubly heavy baryon or a doubly heavy tetraquark are bound by their color-Coulomb potential into a compact diquark. The doubly h…

Charm-meson Triangle Singularity in $e^{+} e^{-}$ Annihilation into $D^{* 0} D ˉ^{0} + γ$

Eric Braaten, Li-Ping He, Kevin Ingles +1

We calculate the cross section for $e^{+} e^{-}$ annihilation into $D^{* 0} D ˉ^{0} + γ$ at center-of-mass energies near the $D^{* 0} D ˉ^{* 0}$ threshold under the assumption that $X(…
