The project SQuHadron deals with generalization of standard fragmentation functions, which have already and widely been used as tools to access the internal structure of the hadrons.
Their generalization will turn them into much more sophisticated “probes”, whose phenomenological potential is very timely in the light of the current and future experimental efforts.
The benchmark reactions addressed in the project are electron-positron annihilation and semi-inclusive deep-inelastic scattering. According to the final states, different aspects of hadronization will be studied.
During the implementation of the whole action, specific contributions have been made to:
- the connection between the dynamical properties of quark propagation and hadronization
- the impact of dynamical mass effects on semi-inclusive scattering processes (e.g. how the dynamical mass of a quark affects reactions governed by the strong force)
- the improvement of the theoretical formalism to study processes sensitive to the transverse momentum of quarks and gluons
- the determination of fragmentation functions by using fits to experimental data
- assessing the impact of future experiments on the current knowledge of hadron structure and hadronization
The technical results have been presented in several workshops and conferences, both at the national and international level.
The goals of the action have been disseminated also through outreach events, both in person and via social media (e.g. broadcasted via Youtube).
