In this research, we have investigated the effect of spin orientation of quarks on the production of the Bc(1S) heavy mesons. We have calculated the fragmentation functions at initial scale µ° .Then we have modified to µ these fragmentation functi

In this paper, we present the branching ratio and polarization fraction of two body decay of Bs0 to the vector mesons ϕ(1020) and X(3872) in which the X(3872) meson can be considered as an intermediate resonance in the final decay Bs0→J/ψπ+π−

In this paper, in order to present an application of the next-to-leading order fragmentation function of b¯ heavy quark, we calculate the differential cross section as a function of transverse momentum pT and the integrated cross section for the Bc

Abstract In this paper, the differential cross section of charmed mesons production ( $$D_{s}^{\pm }$$ D s ± , $$D^{0}$$ D 0 , $$D^{*}$$ D ∗ and $$D^{*\pm }$$ D ∗ ± and $$D^{\pm }$$ D ± ) are computed as a function of transverse momentum $$p_{

Sand and dust storms are natural events that occur widely around the world, mostly in dry and bare lands. Over thepast decade a large part of Iran has been affected by this phenomenon, and Tehran has not been excluded from thisevent. Therefore, havin

In this study, the fragmentation functions (FF) for the production of Bc meson (1S and 2S-states) in c → Bc and b → Bc processes at the leading order (LO) and next-to-leading order (NLO) are derived. Moreover, some technical details about the con

In this paper, we present the analytical solutions, based on the Laplace transform method, for the Dokshitzer–Gribov–Lipatov–Altarelli–Parisi evolution equations of the photon at the leading order (LO) and next-to-leading order (NLO) approxim
