“…Also we have no possible absorptive corrections in the pion-pion final elastic channel, since the central mass is low, and also there is a lack of data on this process to define parameters of the model. Nevertheless we will consider these corrections in further works, as it was done by some authors recently [23], since they could play significant role for masses less than 1 GeV.…”

Calculations of the central exclusive diffractive di-pion continuum production are presented in the Regge-eikonal approach. Data from ISR, STAR, CDF and CMS were analysed and compared with theoretical description. We also consider theoretical predictions for LHC, possible nuances and problems of calculations and prospects of investigations at present and future hadron colliders.PACS 11.55.Jy Regge formalism · 12.40.Nn Regge theory, duality, absorptive/optical models · 13.85.Ni Inclusive production with identified hadrons · 13.85.Lg Total cross sections arXiv:1910.06683v1 [hep-ph]

“…The most common meson-meson interactions are ππ and Kπ . In these two cases, the total cross sections are found using the calculations of Peláez et al [56][57][58]. Below 1.42 GeV for ππ and below 1.8 GeV for Kπ , values of the total cross sections have been tabulated and are found We see that resonances exist for π + π − and K + π − , but not for π + π + and K + π + .…”

“…There is an option in Pythia to also calculate the ππ and Kπ cross sections this way instead of using the default methods of Refs. [57,58], but there are two drawbacks of using this approach. In terms of physics, it is less accurate because it does not take into account interference effects between resonances.…”

A framework for hadronic rescattering in pp collisions

In this article, a framework for hadronic rescattering in the general-purpose Pythia event generator is introduced. The starting point is the recently presented space–time picture of the hadronization process. It is now extended with a tracing of the subsequent motion of the primary hadrons, including both subsequent scattering processes among them and decays of them. The major new component is cross-section parameterizations for a range of possible hadron–hadron combinations, applicable from threshold energies upwards. The production dynamics in these collisions has also been extended to cope with different kinds of low-energy processes. The properties of the model are studied, and some first comparisons with LHC $$\mathrm {p}\mathrm {p}$$ p p data are presented. Whereas it turns out that approximately half of all final particles participated in rescatterings, the net effects in $$\mathrm {p}\mathrm {p}$$ p p events are still rather limited, and only striking in a few distributions. The new code opens up for several future studies, however, such as effects in $$\mathrm {p}$$ p A and AA collisions.

A Dalitz plot analysis of the $$ {D}_s^{+} $$ D s + → π−π+π+ decay is presented. The analysis is based on proton-proton collision data recorded by the LHCb experiment at a centre-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 1.5 fb−1. The resonant structure of the decay is obtained using a quasi-model-independent partial-wave analysis, in which the π+π− S-wave amplitude is parameterised as a generic complex function determined by a fit to the data. The S-wave component is found to be dominant, followed by the contribution from spin-2 resonances and a small contribution from spin-1 resonances. The latter includes the first observation of the $$ {D}_s^{+} $$ D s + → ω(782)π+ channel in the $$ {D}_s^{+} $$ D s + → π−π+π+ decay. The resonant structures of the $$ {D}_s^{+} $$ D s + → π−π+π+ and D+→ π−π+π+ decays are compared, providing information about the mechanisms for the hadron formation in these decays.
