I will talk about some recent flavor physics results from ATLAS and CMS, including the tetraquark search, excited Bc meson search, B meson lifetime measurements and time-dependent CPV measurements. These results deepen our understanding of particle physics in the flavor sector.
Precise measurements of Higgs decays into quarks and gluons are essential
for probing the Yukawa couplings of the Higgs boson and testing the flavor structure of the Standard Model. We investigate the process e+e− → ZH at √s = 240 GeV at a future e+e− Higgs factory, taking the CEPC design as a benchmark. Jet flavor is identified using state-of-the-art particle-level deep neural network...
This talk presents new perspectives on precision nucleon tomography using high-order QCD calculations and jet substructure. We discuss the winner-take-all axis for extending qT subtraction to jet processes, enabling NNNLO predictions for SIDIS and hadron production in DIS. Novel observables such as one-point energy correlators access the nucleon transversity distribution. Furthermore, we...
The $\mu$-$e$ conversion process is one of the most powerful ways to test lepton-flavor-violating (LFV) interactions involving charged leptons. The standard model with massive neutrinos predicts an extremely low rate for $\mu$-$e$ conversion, making this process an excellent probe for testing LFV arising from new physics. Among many theoretical models that can induce LFV, the Supersymmetric...
In this Letter, we present a strategy to decode decay amplitudes with different weak phases in two-body charmed baryon decays, addressing a long-standing challenge to understanding CP violation in this sector.
Using SU(3) flavor symmetry, we disentangle the amplitudes defined through $M=\lambda_s A_s + \lambda_b A_b$ ($\lambda_i = V_{ui}V_{ci}^*$), enabling a data-driven determination of...
The precision determination of the leptonic CP-violating phase $\delta_{CP}$ is one of the main goals of the upcoming long-baseline experiments DUNE and Hyper-Kamiokande. Within the standard three-flavor framework and the usual assumptions on neutrino cross sections -- namely lepton universality and accurate nuclear modeling -- both experiments are projected to reach high sensitivity to...
Motivated by the recent 3.9$\sigma$ evidence for CP violation from the LHCb collaboration in decays of an anti-triplet beauty baryon to a charmonium, an octet baryon, and a pseudoscalar meson,
we perform, for the first time, a systematic analysis of this class of decays within the framework of flavor $SU(3)$ symmetry.
Several predictions for branching ratios and CP violating relations...
We identify a new spin--flavor entanglement structure in $\Lambda_b\to\Lambda D$ decays, formed by the correlation between the $\Lambda$ spin and the neutral-$D$ flavor states ($D=D^0,\overline D^0,D_1,D_2$). The entanglement information is encoded in the decay rates and Lee-Yang parameters of the four neutral-$D$ modes. We then show that the same spin-flavor structure provides a new method...
