Abstract:
I will give a brief introduction to different
experimental physics activities carried out
at Centro Científico Tecnológico de
Valparaiso (CCTVAL) at the Universidad
Técnica Federico Santa María, Valparaiso
Chile which includes collaborative research
activities carried out in different
international labs as well as detector and
detector component design and fabrication.
After that, I will go to the main subject of
the presentation and will talk about the
medium induced hadronization studies with
the CLAS/CLAS12 detector at Jefferson
Lab, Newport News, VA. Atomic nuclei can
be used as spatial analyzers of the
hadronization process in semi-inclusive
deep inelastic scattering. The results of
analysis for the Eg2 experimental data
where electrons and positive pions were
measured from a 5 GeV electron beam
incident on targets of liquid deuterium, C,
Fe, and Pb using CLAS in Hall B will be
described. The broadening of the
transverse momentum and the hadronic
multiplicity ratio of positive pions has been
studied in detail as a function of multiple
kinematic variables. Some interpretation in
terms of the transport of the struck quark
through the nuclear systems will be
discussed as well. At the end I will mention
some future experiments with polarized
targets.
