3. The semileptonic baryonic decay Ds+→pp¯e+νe / Cheng, Hai-Yang ; Kang, Xian-Wei
The decay Ds+→pp¯e+νe with a proton–antiproton pair in the final state is unique in the sense that it is the only semileptonic baryonic decay which is physically allowed in the charmed meson sector. [...]

8. Testing B-violating signatures from exotic instantons in future collidersA. A.’s work was Supported in part by the MIUR research grant “Theoretical Astroparticle Physics" PRIN 2012CPPYP7. XWK's work is partly Supported by the DFG and the NSFC through funds provided to the Sino-German CRC 110 “Symmetries and the Emergence of Structure in QCD” when he was in Jülich, and by MOST, Taiwan, (104-2112-M-001-022) from April 2017. The work by MK was performed within the framework of the Center FRPP Supported by MEPhI Academic Excellence Project (contract 02.03.21.0005, 27.08.2013), Supported by the Ministry of Education and Science of Russian Federation, project 3.472.2014/K and grant RFBR 14-22-03048 / Addazi, Andrea ; Kang, Xian-Wei ; Khlopov, Maxim Yu.
We discuss possible implications of exotic stringy instantons for baryon-violating signatures in future colliders. [...]

9. Branching fractions of semileptonic D and Ds decays from the covariant light-front quark model / Cheng, Hai-Yang ; Kang, Xian-Wei
Based on the predictions of the relevant form factors from the covariant light-front quark model, we show the branching fractions for the D(Ds)→(P,S,V,A)ℓνℓ ( ℓ=e or μ ) decays, where P denotes the pseudoscalar meson, S the scalar meson with a mass above 1 GeV, V the vector meson and A the axial-vector one.

10. Different pole structures in line shapes of the X (3872) / Kang, Xian-Wei ; Oller, J. A.
We introduce a near-threshold parameterization that is more general than the effective-range expansion up to and including the effective range because it can also handle a near-threshold zero in the D0D¯∗0 S -wave. [...]
