We present a comprehensive study of near-threshold structures in the J/\psi J/\psi mass spectrum using the fully reconstructed J/\psi J/\psi \rightarrow 4\mu final state, based on proton-proton collision data at \sqrt{s} = 13 and 13.6 TeV collected by the CMS experiment. With approximately four times more J/\psi pair candidates compared to the previous Run 2 dataset, the combined data sample...
The unique structure of charmed baryons makes them an ideal laboratory for studying QCD in the non-perturbative regime. Research in charm baryon spectroscopy has provided valuable insights into QCD interactions, quark confinement, and broader topics in modern physics. The LHCb detector, dedicated to heavy flavor studies, enables high production rates and efficient detection of charmed...
While the light scalar mesons ($S_0$) are considered to be either ordinary $q\bar q$ or exotic tetraquark states, we investigate the semileptonic decays $D\to S_0 e^+\nu_e$, by taking into account the resonant effects of $S_0\to M_1 M_2$, where $S_0=a_0(980)$, $f_0(980)$, and $f_0(500)/\sigma_0$, and $M_{1(2)}$ represents a pseudoscalar meson. The $D\to S_0$ form factors in the different quark...
One of the primary goals of the AdS/QCD program is to describe hadron spectroscopy accurately. The holographic confining potential, typically written through geometrical deformations or AdS bulk dilaton fields that induce confinement, plays a central role in achieving this. Specifically, the dilaton derivatives govern the large $z$ behavior of the holographic confining potential, where $z$...
We simulate the production of charmed-strange tetraquarks, $T_{cs0}(2900)^0$, $T_{cs1}(2900)^0$, $T_{c\bar{s}}(2900)^{0}$ and $T_{c\bar{s}}(2900)^{++}$ , as hadronic molecules, in $pp$ collisions through the framework of hadronic rescattering. The transverse momentum and rapidity distributions of selected tetraquarks are also studied under different multiple-parton interaction (MPI) tuning....
We study the nonleptonic three-body charmed baryon weak decays of $\mathbf{B}_{c}\rightarrow\mathbf{B}_{n}PP^{\prime}$ and the two-body decays of $\mathbf{B}_{c}\rightarrow\mathbf{B}_{D}P$ under the $SU(3)_{F}$ flavor symmetry,in which $\mathbf{B}_{c}$ denotes the anti-triplet charmed baryon, comprising $(\Xi^{0}_{c},-\Xi^{+}_{c},\Lambda^{+}_{c})$, while $\mathbf{B}_{D}$, $\mathbf{B}_{n}$, and...
