Tomography of high-twist proton structure through $e p$ elastic scattering

Ji-Xin Yu, Shan Cheng, Jia-Jie Han +2

We present the first high-twist study of the proton form factors $F_{1, 2} (Q^{2})$ in $e p$ elastic scattering based on the perturbative QCD $k_{T}$ factorization, $Q^{2}$ being momentum t…

Establishing CP Violation in $b$ -Baryon Decays

Jia-Jie Han, Ji-Xin Yu, Ya Li +4

It is a long-standing puzzle why the {\it CP} violation (CPV) in the baryon system has not yet been definitively established as in the meson one. We demonstrate that individual par…

Weak decays of bottom-charm baryons: $B_{b c} \to B_{b} P$

Jia-Jie Han, Rui-Xiang Zhang, Hua-Yu Jiang +2

After the discovery of the double-charm baryon $Ξ_{cc}^{++}$ by LHCb, one of the most important topics is to search for the bottom-charm baryons which contain a $b$ quark, a $c$ qu…

Rescattering mechanism of weak decays of double-charm baryons

Jia-Jie Han, Hua-Yu Jiang, Wei Liu +2

The doubly charmed baryon $Ξ_{cc}^{++}$ was recently observed by LHCb via the decay processes of $Ξ_{cc}^{++} \to Λ_{c}^{+} K^{-} π^{+} π^{+}$ and $Ξ_{c}^{+} π^{+}$ . These discovery channels were succ…

Branching fractions of $B^{-} \to D^{-} X_{0, 1} (2900)$ and their implications

Yan-Ke Chen, Jia-Jie Han, Qi-Fang Lü +2

The exotic states $X_{0, 1} (2900)$ with the quark flavor of $cs u ˉ d ˉ$ are recently observed in the mass spectrum of $D^{+} K^{-}$ in $B^{-} \to D^{-} D^{+} K^{-}$ by the LHCb collaboration…

Probing Gravitational Lensing of the CMB with SDSS-IV Quasars

Jiashu Han, Simone Ferraro, Elena Giusarma +1

We study the cross-correlation between the Planck CMB lensing convergence map and the eBOSS quasar overdensity obtained from the Sloan Digital Sky Survey (SDSS) IV, in the redshift…
