Studying hadronization at LHCb
ORAL
Abstract
The LHCb experiment at the Large Hadron Collider (LHC) is suited for studying how hadrons are formed from scattered quarks and gluons, collectively referred to as partons, in energetic proton-proton collisions. The hadronization process is a non-perturbative phenomenon, unlike hard scattering of partons and their shower processes and therefore can be learned from measurements, such as those involving jet sub-structure. Equipped with a forward spectrometer, the LHCb experiment achieves a transverse momentum resolution of $\frac{\Delta p_T}{p_T}< $1 % up to 200 GeV/c for charged tracks and a jet $p_T$ resolution of $<$15 %. This along with excellent particle identification capabilities offers a unique opportunity to measure with great precision hadronization variables $j_T$, z and r, defined to characterize multi-dimensional hadronization processes and their flavor dependence within jets. This talk will present recently published results for measurements of nonidentified hadrons within light quark-initiated jets as well as the status of other ongoing hadronization measurements at LHCb.
