For each case, the numerator always contains at least one more strange quark than the denominator, and the results obtained from JE, UE and inclusive selections are compared. Similarly to the baryon-to-meson yield ratios shown in the upper three panels of the same figure, the baryon-to-...
Furthermore, the fragmentation properties of different parton species in the hot-dense medium created in a heavy-ion collision are also expected to be different for quark- and gluon-initiated jets. Because of its larger colour charge, a gluon jet is expected to lose more energy than a quark ...
2.4. 〈VV〉〈V〉 structure We can estimate the weights for the 〈VV〉〈V〉 structure proceeding analogously as in the preceding subsection. Thus, the contributions carrying the ω,ϕ and ⁎K⁎0 vectors are: • ω meson(11)⁎⁎2ω(5P(S=0)+2P(S=2))[−36(ρρ)(I=0)...

We investigate B→K0*(1430)K* decays in the perturbative QCD (pQCD) factorization approach, where B denotes Bu, Bd, and Bs mesons, respectively, and the scalar K0*(1430) is considered as a meson based on the model of the conventional two-quark structure. With the light-cone distribution...
Based on the assumption of two-quark structure of the scalar meson K*0(1430),we calculate the CP-averaged branching ratios for B→K0*(1430)η(') decays in the framework of the perturbative QCD(pQCD) approach here.We perform the evaluations in two scenarios for the scalar meson spectrum....
Novel Tcs and Tcs candidates in a constituent-quark-model-based meson-meson coupled-channels calculation Using proton-proton collisions at center-of-mass energies 7, 8, and 13 TeV, with a total integrated luminosity of 9 fb-1, the LHCb collaboration has perfor... PG Ortega,DR Entem,FSJ ...
