Effects of color reconnection on hadron flavor observables
(2015) In Physical Review D (Particles, Fields, Gravitation and Cosmology) 92(9).- Abstract
- We present a series of observables for soft inclusive physics, and utilize them for comparison between two recently developed color reconnection models: the new color reconnection model in Pythia and the DIPSY rope hadronization model. The observables are ratios of identified hadron yields as a function of the final-state activity, as measured by the charged multiplicity. Since both considered models have a nontrivial dependence on the final-state activity, the above observables serve as excellent probes to test the effect of these models. Both models show a clear baryon enhancement with increasing multiplicity, while only the DIPSY rope model leads to a strangeness enhancement. Flowlike patterns, previously found to be connected to color... (More)

Flowlike patterns, previously found to be connected to color reconnection models, are investigated for the new models. Only Pythia shows a p(perpendicular to)-dependent enhancement of the Lambda/K ratio as the final-state activity increases, with the enhancement being largest in the mid-p(perpendicular to) region.
