In the past two decades, a plethora of hadronic states beyond the conventional quark model
of qq ̄ mesons and qqq baryons have been observed experimentally, which motivated …

We propose that the X (3915) observed in the J/ψ ω channel is the same state as the χ c 2
(3930), and the X (3960), observed in the D s+ D s-channel, is an S-wave D s+ D s-hadronic …

The spectrum of the charmed meson-(anti) meson system is a fundamental tool for
disentangling the nature of a few exotic hadrons, including the recently discovered T …

A near-threshold enhancement in the D s+ D s-system, dubbed as X (3960), is observed by
the LHCb collaboration recently. A combined analysis on χ c 0 (3930)(→ D+ D-), X (3960)(→ …

We review the semi-inclusive hadroproduction of a neutral hidden-flavor tetraquark with light
and heavy quark flavor at the HL-LHC, accompanied by another heavy hadron or a light …

Inspired by the great progress in the observations of charmonium-like states in recent years,
we perform a systematic analysis about the ground states and the first radially excited states …

We investigate the inclusive production of fully charmed tetraquarks,\(T_ {4c}(0^{++})\) or\(T_
{4c}(2^{++})\) radial excitations, in high-energy proton collisions. We build our study upon …

In this work, a study of the D s D¯ s interaction and its couplings to the channels DD¯ and
J/ψ ϕ is performed in a quasipotential Bethe–Salpeter equation approach. The D s+ D s-and …
