Fragmentation functions: Experiments & Phenomenology
- Umberto D'Alesio (Istituto Nazionale di Fisica Nucleare)
Fragmentation functions as well as parton distributions are fundamental non-perturbative objects that allow knowledge obtained from different processes to be used for the understanding of other processes through QCD factorization theorems. They also serve as a test bed of the theoretical framework. Recent results on hadronziation from several key processes: hadron-hadron interaction, e+e-...
Fragmentation functions play a crucial role in describing the hadronization process.
We report the measurements of normalized differential cross sections of inclusive pi0, Ks, and eta production as a function of hadron momentum at six energy points with q^2 transfer from 5 to 13 GeV^2 at BESIII. In addition, new recent results of single inclusive charged pions and kaons at center of mass...
In this talk, we present some recent updates on the TMD fragmentation functions (FFs), namely the unpolarized and the Collins FFs. The impact of $A_N$ data measured in inclusive processes is estimated through an extended version of the Bayesian reweighting method, and the universality properties of these functions are tested through estimates of the Collins asimmetry for $\pi$-jet production...
