Effects of Overlapping Strings in pp Collisions
read the original abstract
In models for hadron collisions based on string hadronization, the strings are usually treated as independent, allowing no interaction between the confined colour fields. In studies of nucleus collisions it has been suggested that strings close in space can fuse to form "colour ropes". Such ropes are expected to give more strange particles and baryons, which also has been suggested as a signal for plasma formation. Overlapping strings can also be expected in pp collisions, where usually no phase transition is expected. In particular at the high LHC energies the expected density of strings is quite high. To investigate possible effects of rope formation, we present a model in which strings are allowed to combine into higher multiplets, giving rise to increased production of baryons and strangeness, or recombine into singlet structures and vanish. Also a crude model for strings recombining into junction structures is considered, again giving rise to increased baryon production. The models are implemented in the DIPSY MC event generator, using PYTHIA 8 for hadronization, and comparison to pp minimum bias data, reveals improvement in the description of identified particle spectra.

A more effective QCD string at colliders: Decay of excited strings and the worldsheet axion
Excitations of the worldsheet axion in an effective QCD string theory produce a phase-dependent effective tension that exponentially modifies the rate of string breaking via quark pair nucleation.

Sequential Y(nS) suppression in high-multiplicity pp collisions: the experimental case for an early, globally correlated medium
Multi-differential tests on Υ(nS) and ψ(2S)/J/ψ suppression in high-multiplicity pp collisions rule out standard hadronic and string models in favor of an early globally correlated partonic medium.
