Abstract

We present a quantitative analysis of masses and decays of $cc \bar c \bar c$ tetraquarks, with diquarks and antidiquarks in S and P wave. We study explicitely the decays of the $4P-J^{PC}=3^{--},~2^{--}$ into 4 muons and into hidden- and open-charm mesons and estimate its width and branching ratios. Based on our results and with the present sensitivity, LHCb, CMS and ATLAS should detect the $4P-J^{PC}=3^{--},~2^{--}$ fully-charmed tetraquark. We note that one decay channel of the $4P-J^{PC}=2^{--}$could lead to the identification of the (still controversial) $χ_{c1}(2P)$.

Dark Photon mediated Inelastic Dark Matter in Cosmology, Astrophysics and Colliders

We explore the phenomenology of Dark Photon iDM ($A^\prime$IDM) where the Standard Model (SM) is extended by a dark sector containing an additional $U(1)_D$ gauge symmetry with coupling $α_D$ under which all SM particles are neutral, and that couples to the SM hypercharge gauge boson through a kinetic mixing parameter $ε$. The model contains two Majorana states $χ_1$ and $χ_2$ with $δ=M_{χ_2}-M_{χ_1}>0$ and $χ_1$ the dark matter candidate, and a dark photon $A^{\prime}$ with mass $M_{A^{\prime}}$. Our analysis represents an integration of existing ones, where only specific benchmarks of the A'IDM scenario have been discussed. We perform a complete scan of the parameters of the model ($M_{χ_1}$, $δ$, $M_{A^{\prime}}$, $ε$, $α_D$) and discuss the $χ_1$ relic abundance, its direct and indirect searches, as well as potential signals from astrophysics and accelerators. Our scan shows that $α_D=α_{EM}$ is not disfavored, as some previous analyses, limited to specific benchmarks, may suggest. We also find that when the $χ_1$ relic density matches observation direct and indirect searches are not kinematically accessible. On the other hand we find that the projected luminosity of FASER, a detector searching for Long Lived Particles (LLP) decay at the LHC, can probe or rule out the parameters space of the model for $M_{χ_1}\lesssim$ 7 GeV, 100 MeV$\lesssimδ\lesssim$300 MeV and $M_{A^\prime}\lesssim$25 GeV. This range of parameter could be significantly extended by the FASER 2 upgrade proposed for the High-Luminosity phase at the LHC. The parameter space probed by LLP seaches partially overlaps with that probed by $χ_1$ capture in neutron stars.

Reassessing the $X(2370)$ in $J/ψ\toγK_S^0K_S^0π^0$ beyond the one-dimensional mass projections

The BESIII Collaboration recently extracted the properties of the $X(2370)$ from a fit to the one-dimensional $K_S^0K_S^0π^0$ invariant-mass spectrum in $J/ψ\toγK_S^0K_S^0π^0$. The intermediate two-body structures visible in the mass correlations, including the $K_0^*(1430)$ bands, require a coherent treatment of cross-channel interference when interpreting the enhancement near 2.3 GeV. We reassess the need for an additional $X(2370)$ contribution by fitting the published data using an effective coupled-channel framework with an approximate detection efficiency depending on the three-body invariant mass. The three-body parent amplitude is parameterized using a $K$-matrix that describes scattering among several quasi-two-body channels. The seven- and eight-bare-state models give similar mass distributions. Adding the eighth bare state lowers the Poisson deviance by 1.22% and produces an additional pole at $E=(2419-i152)$ MeV, substantially broader than the $X(2370)$ mass-width reference. This pole is model-dependent, and its identification with the $X(2370)$ is not clear. The present analysis does not establish the need for an additional $X(2370)$ contribution in $J/ψ\toγK_S^0K_S^0π^0$, thereby weakening the flavor-singlet argument based on the suppression of $K^*\bar K$ relative to the total $K\bar Kπ$ contribution. A more comprehensive experimental amplitude analysis, incorporating coherent interference, mass and angular correlations, and detector effects across related decay channels, is needed to establish the role and decay properties of the $X(2370)$.

Gauge Interactions Involving New Vector and Pseudoscalar Particles

The Vector gauge bosons $Z'$ and axion-like particles (ALPs) $a$ are predicted by the $U(1)_X$ gauge extension and Peccei-Quinn (PQ) models, respectively. We focus on the interactions of the $Z'$ boson and the $a$ particle with the $W^\pm$ gauge boson, and investigate the production cross section and related kinematic distributions for the $Z'/a\to W^+W^-$ decay process at hadron colliders. We consider the angular distributions of charged leptons in the final states corresponding to the semileptonic and fully leptonic decays of the $W^\pm$ boson, separately. The study shows that, in the associated production processes of $Z'/a$ with $W^+$ or $Z$ bosons, the angular distributions of final-state leptons can serve as an important observable for probing new gauge interactions, and can also provide a criterion to distinguish vector particles from pseudoscalar particles.
