Perturbative QCD Fragmentation Functions for B c and B ∗ c Production
نویسندگان
چکیده
The dominant production mechanism for ¯ bc bound states in high energy processes is the production of a high energy ¯ b or c quark, followed by its fragmentation into the ¯ bc state. We calculate the fragmentation functions for the production of the S-wave states B c and B * c to leading order in the QCD coupling constant. The fragmentation probabilities for ¯ b → B c and ¯ b → B * c are approximately 2.2 × 10 −4 and 3.1 × 10 −4 , while those for c → B c and c → B * c are smaller by almost two orders of magnitude.

Meson B fragmentation function with consideration of mass corrections
Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons. For this reason, in this paper we will study the production process of this meson in a phenomenological approach using the experimental data from electron-positron annihilation. In this regards, we shall calculat...

Studying the production or decay processes of heavy quarkonia (the bound state of heavy quark-antiquark) is a powerful tool to test our understanding of strong interaction dynamics and QCD theory. Fragmentation is the dominant production mechanism for heavy quarkonia with large transverse momentum. The fragmentation refers to the production process of a parton with high transverse momentum whic...
متن کاملFragmentation Production of Ωccc and Ωbbb Baryons
The Λ baryons with a single heavy flavor which transfer the quark polarization, have been studied both theoretically and experimentally. The Ξ’s with two heavy constituents are well treated in quark-diquark model. In this work we study the production of triply heavy baryons in the perturbative QCD regime and calculate the fragmentation functions for Ωccc and Ωbbb in the c and b quark fragmentat...
متن کاملTHE ROLE OF QUARK POLARIZATION IN HEAVY QUARK FRAGMENTATION
We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.
متن کاملBc meson production at the Tevatron Revisited
CDF recently measured the quantity σ(B + c ) σ(B+) BR(B c →J/ψlν) BR(B+→J/ψK+) , from which we determine the ratio σ(B + c ) σ(b̄) to be (2.08 −0.95) × 10−3. If we interpret this ratio as a fragmentation probability, we show that this ratio is consistent with the prediction by perturbative QCD Bc fragmentation function of Braaten, Cheung, and Yuan. We also estimate the parameter mc (charm quark ...
