2. Complete computation of planar two-loop six-point massless integrals
扬 张 (中国科学技术大学)
29/03/2025, 09:10

We compute all planar two-loop six-point massless integrals via canonical differential equations. The integral basis with uniform transcendentality is determined via the D-dimensional upgrading of dual conformal integrals and the Baikov representation analysis. The analytic boundary values are determined and all planar two-loop six-point massless planar are calculated as iterative integrals....

7. Leptogenesis from symmetry non-restoration
伟 晁 (北京师范大学)
29/03/2025, 11:10

In this talk, I will present a Leptogenesis scenario, which does not need primordial B-L asymmetry in the early Universe, and does not need the existence of right-handed neutrinos. In this case, the baryon asymmetry is generated by the requirement that the electron Yukawa interction enters thermal equilibrium after the quench of the electroweak sphaleron.

15. Novel approach to probing top-philic resonances with boosted four-top tagging
Dr 浩林 李 (中山大学)
29/03/2025, 15:00

We introduce a novel search strategy for heavy top-philic resonances that induce new contributions to four-top production at the LHC. We capitalize on recent advances in top-tagging performance to demonstrate that the final state, that is expected to be boosted based on current limits, can be fully reconstructed and exploited. Notably, our approach promises bounds on new physics cross sections...
16. Search for Exotic Gauge Particles at the Future Colliders
洪蕾 李 (济南大学)
29/03/2025, 15:40

The study of exotic gauge bosons beyond the Standard Model have always been of great interest. Future muon colliders will have a significant advantage in discovering exotic particles. We study the properties of $Z^\prime$ boson with the process of $\mu^+ \mu^- \rightarrow q \bar{q}$, $\mu^+ \mu^- \rightarrow l^+ l^-$, $\mu^+ \mu^- \rightarrow Z H$ and $\mu^+ \mu^- \rightarrow W^+ W^-$. ...

1. celestial massive amplitudes
炜 樊 (江苏科技大学)
29/03/2025, 16:20

Here we discuss the 3pt celestial amplitude of two massive scalars and one massless scalar. In the massless limit $m\to 0$ for one of the massive scalars, the gamma function $\Gamma(1-\Delta)$ appears. By requiring the resulting amplitude to be well-defined, that is it goes to the 3pt amplitude of arXiv:2312.08597, the scaling dimension of this massive scalar has to be conformally soft...
10. New version of NeatIBP: a novel tool for Feynman integral computation
子昊 吴 (国科大杭州高等研究院)
29/03/2025, 17:00

The integration-by-parts (IBP) reduction is one of the bottleneck steps in the evaluation of multi-loop Feynman integrals. NeatIBP is a program based on the syzygy method for IBP reduction. It generates much smaller IBP systems compared to traditional Laporta's algorithm, which helps reduce the computation cost of IBP reduction. In this talk, I will present the new version of NeatIBP. It is...
3. An Analytic Computation of Three-Loop Five-Point Feynman Integrals
Mr 涌群 徐 (中国科学技术大学)
29/03/2025, 17:15

We evaluate the three-loop five-point pentagon-box-box massless integral family in the dimensional regularization scheme, via canonical differential equation. We use tools from computational algebraic geometry to enable the necessary integral reductions. The boundary values of the differential equation are determined analytically in the Euclidean region. To express the final...

12. Categorizing representations of scalar SU(3)_f mesons by decays
晓 喻 (国科大杭州高等研究院)
29/03/2025, 18:15

The scalar mesons are established for a long time, but their nature is still an open question. In this paper, we investigate the potential of categorizing their $SU(3)_f$ representations via $J/\psi \to SV $and $\gamma S$, offering a criterion that may illuminate this issue. Here, $S (V)$ denotes scalar (vector) mesons. Using the $SU(3)_f$ symmetry with the current data, we find that...

11. Long-lived heavy neutral leptons from axionlike particles at the LHC and Belle II
泽人 王 (合肥工业大学)
30/03/2025, 10:40

In hidden-sector models, axion-like particles (ALPs) can couple to heavy neutral
leptons (HNLs), leading to rich phenomenologies. We study ALPs produced from D- and B-meson decays via quark-favor-violating couplings, and decaying exclusively into a pair of HNLs which mix with active neutrinos. The ALP can be either short- or long-lived, depending on the masses of the ALP and the HNL, as well...

9. Next-to-leading order QCD corrections to Bc* → J/ψ form factors
Dr 伟 陶 (河南师范大学)
30/03/2025, 14:00

Within the framework of Non-Relativistic Quantum Chromodynamics (NRQCD) factorization,
we calculate the next-to-leading order (NLO) perturbative QCD corrections to the form factors for
the semileptonic decays of Bc* into J/ψ via (axial-)vector and (axial-)tensor currents. We obtain the
complete analytical results for the form factors up to NLO, and provide their asymptotic expressions
in...

Dr 鸿浩 马 (广西师范大学)

X（3872），作为四夸克的候选者，其产生和衰变等性质被实验和理论广泛研究。我们在NRQCD框架下，通过Higgs和弱玻色子衰变研究了双粲紧致四夸克态的间接产生机制，并分别在LHC和CEPC上预言了其分支比和产生率等。基于共线因子化，利用两种碎裂函数方法，我们对全粲四夸克态的间接产生性质也进行了深入的研究。通过此报告将详细介绍近期我们关于四夸克态间接产生的理论研究工作。
8. Unified interpretation of the muon g − 2 anomaly and 95 GeV excesses in the general next-to-minimal supersymmetric standard model
经伟 连 (河南科技学院 and 河南师范大学)
30/03/2025, 15:40

We investigate three intriguing anomalies within the framework of the general next-to-minimal supersymmetric standard model. These anomalies include a significant deviation of the experimental results for the muon anomalous magnetic moment from its standard model prediction, with a confidence level of 5.1σ; a joint observation by the CMS and ATLAS Collaborations of a diphoton excess with a...
6. Footprints of vector-like quark models
Dr 世平 和 (太原理工大学)
30/03/2025, 16:00

Vector-like quarks (VLQs) are ubiquitous in many new physics models, such as grand unified theory, composite Higgs models, extra dimension theory, and so on. In minimal VLQ models, only seven types of representations can induce the mixing with standard model quarks. In non-minimal VLQ models, we can also introduce new scalar fields. The VLQ models can lead to rich phenomenology in electroweak...
