14:25 → 14:50 $b \to sll$ angular analyses on CMS

The FCNC process $b \to sll$ has been known as a sensitive probe of new physics. And recent angular analyses results of the process showed intriguing deviation from the SM prediction. Motivated by these evidence of new physics, more and more angular analyses are performed, based on data collected by CMS in LHC Run2. With a large amount of CMS Run2 data and updated analysing procedure, those new analyses are promising to present more striking results.

15:15 → 15:35 Studying the $b \to s \ell^+ \ell^-$ Anomalies and $(g-2)_\mu$ in RPV-MSSM Framework with Inverse Seesaw

Inspired by the recent experimental results which show deviations from the standard model (SM) predictions of $b\rightarrow s \ell^+\ell^-$ transitions, we study the $R$-parity violating minimal supersymmetric standard model (RPV-MSSM) extended by the inverse seesaw mechanisms. The trilinear $R$-parity violating terms together with the chiral mixings of sneutrinos induce the loop contributions to the $b\rightarrow s \ell^+\ell^-$ anomaly. We study the parameter space of the single-parameter scenario $C_{9,\mu}=-C_{10,\mu}=C_{\rm V}$ and the double-parameter scenario $(C_{\rm V},C_{\rm U})$ respectively, constrained by other experimental data such as $B_s-\bar{B}_s$ mixing, $B\rightarrow X_s \gamma$ decay, the lepton flavour violating decays, etc.. Both the single-parameter scenario and double-parameter scenario can resolve the long existed muon anomalous magnetic moment problem as well and allow the anomalous $t\rightarrow cg$ transition to reach the sensitivity at the Future Circular hadron-hadron Collider (FCC-hh).

11:10 → 11:30 Time-reversal asymmetries and angular distributions in $\Lambda_b\to \Lambda V$

We study the spin correlations to probe time-reversal (T) asymmetries in the decays of $\Lambda_b \to \Lambda V ~(V=\phi, \rho^0, \omega, K^{*0})$. The eigenstates of the T-odd operators are obtained along with definite angular momenta. We obtain the T-odd spin correlations from the complex phases among the helicity amplitudes. We give the angular distributions of $\Lambda_b \to \Lambda(\to p \pi^-)V(\to PP')$ and show the corresponding spin correlations, where $P^{(\prime)}$ are the pseudoscalar mesons. Due to the helicity conservation of the $s$ quark in $\Lambda$, we deduce that the polarization asymmetries of $\Lambda$ are close to $-1$. Since the decay of $\Lambda_b \to \Lambda \phi$ in the standard model~(SM) is dictated by the single weak phase from the product of CKM elements, $V_{tb}V_{ts}^*$, the true T and CP asymmetries are suppressed, providing a clean background to test the SM and search for new physics. In the factorization approach, as the helicity amplitudes in the SM share the same complex phase, T-violating effects are absent. Nonetheless, the experimental branching ratio of $Br(\Lambda_b \to \Lambda \phi) = (5.18\pm 1.29 )\times 10^{-6}$ suggests that the nonfactorizable effects or some new physics play an important role. By parametrizing the nonfactorizable contributions with the effective color number, we calculate the branching ratios and direct CP asymmetries. We also explore the possible T-violating effects from new physics.

Then Using the constrained NP coupling parameters, we report the numerical results and NP effects on various observables related to the processes $\Omega_b \to \Omega_c l \nu_l$ and $\sigma_b \to Sigma_c l \nu_l$.

11:50 → 12:10 $\Lambda_b \to p$ transition form factors in the perturbative QCD

In this work, we calculated the $\Lambda_b \to p$ transition form factors in the perturbative QCD (PQCD) approach. Contributions beyond leading-twist light-cone distribution amplitudes (LCDAs) of both proton and $\Lambda_b$ baryon are systematically investigated. The results are consistent with other methods. The dominant contributions of form factors $F_1$, $F_2$, $G_1$ and $G_2$ come from the twist-5 LCDAs of proton and the twist-4 LCDA of $\Lambda_b$ baryon, while for those of $F_3$ and $G_3$, coming from both twist-4 LCDAs of proton and $\Lambda_b$ baryon. We found that the higher power corrections are much more important compared with the leading power in the decay of heavy baryon.

09:40 → 10:00 $CP$ asymmetry in the angular distributions of $\tau\to K_S\pi\nu_\tau$ decays

In this work, we proceed to study the $CP$ asymmetry in the angular distributions of $\tau\to K_S\pi\nu_\tau$ decays within a general effective field theory framework including four-fermion operators up to dimension-six. It is found that, besides the commonly considered scalar-vector interference, the tensor-scalar interference can also produce a nonzero $CP$ asymmetry in the angular distributions, in the presence of complex couplings. Using the dispersive representations of the $K\pi$ form factors as inputs, and taking into account the detector efficiencies of the Belle measurement, we firstly update our previous SM predictions for the $CP$ asymmetries in the same four $K\pi$ invariant-mass bins as set by the Belle collaboration. Bounds on the effective couplings of the nonstandard scalar and tensor interactions are then obtained under the combined constraints from the $CP$ asymmetries measured in the four bins and the branching ratio of $\tau^-\to K_S\pi^-\nu_\tau$ decay, with the numerical results given respectively by $\mathrm{Im}[\hat{\epsilon}_S]=-0.008\pm0.027$ and $\mathrm{Im}[\hat{\epsilon}_T]=0.03\pm0.12$, at the renormalization scale $\mu=2~\mathrm{GeV}$ in the $\mathrm{\overline{MS}}$ scheme. Using these best-fit values, we also find that the distributions of the $CP$ asymmetries can deviate significantly from the SM prediction in almost the whole $K\pi$ invariant-mass regions. The current bounds are still plagued by large experimental uncertainties, but will be improved with more precise measurements from the Belle II experiment as well as the proposed Tera-Z and STCF facilities.
