13. A comprehensive analysis of two-body doubly charmful baryonic $B$ decays

Yu-Kuo Hsiao (Shanxi Normal University)

HF&QCD

The charmed baryon pairs in $B\to{\bf B}c\bar{\bf B}'c$ decays can be classified into three categories: (i)~${\bf B}{\bar 3c}\bar{\bf B}'{\bar 3c}$, (ii)~${\bf B}{6c}\bar{\bf B}'{\bar 3c}+{\bf B}{\bar 3c}\bar{\bf B}'{6c}$, and (iii)~${\bf B}{6c}\bar{\bf B}'{6c}$, where ${\bf B}{\bar 3c}$ and ${\bf B}{6c}$ denote the anti-triplet and sextet charmed baryons, respectively. Until recently, all...

7. Continuum-Limit Heavy-Meson LCDAs from Lattice QCD

浩飞 高 (上海交通大学)

Hadron Structure

Heavy-meson light-cone distribution amplitudes are essential nonperturbative inputs for precision heavy-flavor phenomenology. We present a first-principles lattice-QCD determination of heavy-meson LCDAs in both QCD and HQET using the HQLaMET framework. Simulations on multiple ensembles enable controlled continuum, chiral, and infinite-momentum extrapolations. Improved lattice techniques...

15. Energy flow in B-meson inclusive decays

帅 赵 (天津大学)

Heavy Flavor

Inclusive B decays provide precision tests of heavy-quark dynamics and access to fundamental flavor parameters. This talk introduces endpoint factorization and the energy correlators, then presents the B-decay tagged energy correlator (BTEC), which resolves hadronic energy flow relative to the photon recoil axis in $B\to X_s\gamma$. For the direct-photon contribution at the natural collinear...

10. Exploring the neutron momentum distribution in nuclei through γn → π^− p

书曼 胡 (兰州大学)

Hadron Structure

The high-momentum components and associated off-shell effects arising from nucleon-nucleon short-range correlations (SRCs) are important features of nuclear structure beyond the mean-field approximation. Existing studies have primarily relied on electron scattering, while the sensitivity of meson scattering to SRCs requires further investigation in specific reactions. In this report, we...

1. Factorization and Power Corrections for Baryon Quasi-Distribution Amplitudes

Yuji Shi (华东理工大学)

Hadron Structure

Light-cone distribution amplitudes (LCDAs) are essential to precision phenomenology in heavy baryon decays. In this work, we derive a factorization formula connecting the leading-twist QCD LCDA to the boosted HQET LCDA of the $\Lambda_b$ baryon in the peak region. We demonstrate a significant simplification of the matching procedure by applying the method-of-regions to perturbative...

16. Heavy-meson molecules with dynamical pions

Yan-Ke Chen (Peking University)

Phenomenology

We investigate heavy-meson molecules by treating the pion as a dynamical degree of freedom. We construct an energy-independent Hamiltonian that couples the two- and three-body Fock spaces. The two-body sector contains a pseudoscalar meson and a vector meson $H_1H_2^{*}$, while the three-body sector consists of two pseudoscalar mesons and a pion $H_1H_2 \pi$. The $H^*$ self-energy, the...

9. Model-Independent Reconstruction of the Proton-Proton Source Function via Regularized Inversion

Ao-Sheng Xiong (兰州大学)

Hadron Structure

Femtoscopy provides a unique laboratory for studying hadron-hadron interactions via two-particle correlation functions (CFs), yet its predictive power is fundamentally limited by the unknown emission source $\mathcal{S}(r)$. We present a model-independent reconstruction of the proton-proton source by formulating the Koonin-Pratt equation as an inverse problem, stabilized through Tikhonov...

5. Next-to-leading-order QCD corrections to doubly heavy baryon production in $W^+$-boson decays

鸿浩 马 (广西师范大学)

QCD

Predicting the production of doubly heavy baryons in electroweak-boson decays with precision requires a systematic treatment of QCD radiative corrections, especially for guiding experimental searches for the yet-unobserved $\Xi_{bc}$ baryon in large $W$-boson datasets. In this work, we compute the next-to-leading-order (NLO) QCD corrections to the inclusive decay channels $W^+\to\Xi_{cc}+\bar...

4. Non-perturbative Hamiltonian renormalization in the basis light-front approach: Application to the $\Omega_{ccc}$ baryon

Yang Li (University of Science and Technology of China)

Heavy Flavor

Within the basis light-front Hamiltonian approach, we investigate the structure and properties of the triply charmed baryon $\Omega_{ccc}$. Our framework begins with a phenomenological quark-quark Hamiltonian comprising a one-gluon exchange interaction and a holographic confinement potential, with parameters fully constrained by fits to the meson mass spectrum. While extending this same...

3. Production of $D_s\bar{D}_s$ and $D\bar{D}$ bound states in $B$ decays within a Bethe-Salpeter model

振洋 王 (宁波大学)

Heavy Flavor

Within a Bethe-Salpeter model, we investigate the production of possible $D_s\bar{D}_s$ $(X_{s\bar{s}})$ and $D\bar{D}$ $(X_{q\bar{q}})$ bound states in $B$ decays. The bound state properties of the two heavy meson systems are studied in the one-boson-exchange kernel, and the resulting normalized Bethe--Salpeter wave functions are used to calculate the branching fractions of $B^+\to X_{s\bar...

8. QCD evolutions in the diffractive dijet production in photon-nucleus collisions

Shu-Yi WEI (Shandong University)

QCD

We study the diffractive production of back-to-back dijet at high $P_\perp$ in photon-nucleus collisions within the CGC framework. At leading order, this process exhibits TMD factorization, where the momentum imbalance between the jets is described by a diffractive gluon TMD distribution sensitive to gluon saturation. Next-to-leading-order corrections reveal a complex interplay of three...

11. Topological Diagrams and Hadronic Rescattering: A Framework for CP Violation in Charmed Baryon Decays

迪 王 (湖南师范大学)

Phenomenology

Establishing CP violation in the charmed baryon sector remains a central challenge in particle physics.
In this work, we develop a framework for CP violation in charmed baryon decays by combining quark-level topological amplitudes with the hadron-level rescattering mechanism.
The two descriptions are connected through (1,1)-rank amplitudes, which are linear combinations of topological...

14. Unraveling weak radiative hyperon decays with broken flavor symmetry

Jin Sun (Shanghai Joao Tong University)

Phenomenology

We present a broken $SU(3)$ flavor analysis of weak radiative decays of spin-1/2 hyperons, incorporating current-current and electromagnetic-penguin contributions as well as charge- and mass-insertion effects. Six independent reduced amplitudes describe all decay channels, while a minimal relation between the parity-conserving and parity-violating form factors reduces to eight free...
