Measurement of the $e^+e^- \to K^+K^-\pi^+\pi^-$ cross section with the CMD-3 detector at the VEPP-2000 collider

Shemyakin, D.N. ; Fedotovich, G.V. ; Akhmetshin, R.R. ; et al.

Phys.Lett.B 756 (2016) 153-160, 2016.

Inspire Record 1395968 DOI 10.17182/hepdata.76553

The process $e^+e^- \to K^+K^-\pi^+\pi^-$ has been studied in the center-of-mass energy range from 1500 to 2000\,MeV using a data sample of 23 pb$^{-1}$ collected with the CMD-3 detector at the VEPP-2000 $e^+e^-$ collider. Using about 24000 selected events, the $e^+e^- \to K^+K^-\pi^+\pi^-$ cross section has been measured with a systematic uncertainty decreasing from 11.7\% at 1500-1600\,MeV to 6.1\% above 1800\,MeV. A preliminary study of $K^+K^-\pi^+\pi^-$ production dynamics has been performed.

pi+ + d --> p + p reaction between 18-MeV and 44-MeV.

Pasyuk, E.A. ; Alexakhin, V.Yu. ; Gogolev, S.I. ; et al.

Phys.Rev.C 55 (1997) 1026-1032, 1997.

Inspire Record 425528 DOI 10.17182/hepdata.25740

A study of the reaction pi+ + d --> p + p has been performed in the energy range of 18 - 44 MeV. Total cross sections and differential cross sections at six angles have been measured at 15 energies with an energy increment of 1 - 2 MeV. This is the most systematic data set in this energy range. No structure in the energy dependence of the cross section has been observed within the accuracy of this experiment.

Rescattering probed by the emission of slow target associated particles in high-energy heavy ion interactions

The EMU01 collaboration Adamovich, M.I ; Aggarwal, M.M ; Alexandrov, Y.A ; et al.

Phys.Lett.B 363 (1995) 230-236, 1995.

Inspire Record 406952 DOI 10.17182/hepdata.28438

In this letter the distribution of slow target associated particles emitted in Au + Emulsion interactions at 11.6 A GeV/ c is studied. The three models RQMD, FRITIOF and VENUS are used for comparisons and especially their treatment of rescattering is investigated.

Total cross-section of the reaction pi+ d ---> p p at pion energies 26-MeV to 40-MeV

Gogolev, S.I. ; Gostkin, M.I. ; Haysak, I.I. ; et al.

Phys.Lett.B 300 (1993) 24-28, 1993.

Inspire Record 361849 DOI 10.17182/hepdata.28959

Total cross sections for the reaction π + d → pp have been measured for incident pion energies T π =26.5, 28.5, 30.5, 32.5 and 39.5 MeV. The data are in good agreement with previous experiments. There is some indication of a peculiarity in the energy dependence of the total cross section near incident pion energy T π =30 MeV.

Limiting Fragmentation in Oxygen Induced Emulsion Interactions at 14.6-a/{GeV}, 60-a/{GeV} and 200-a/{GeV}

The EMU01 collaboration Adamovich, M.I. ; Aggarwal, M.M. ; Arora, R. ; et al.

Phys.Rev.Lett. 62 (1989) 2801, 1989.

Inspire Record 268021 DOI 10.17182/hepdata.20041

Pseudorapidity distributions of relativistic singly charged particles in oxygen-induced emulsion interactions at 14.6, 60, and 200 GeV/nucleon are studied. Limiting fragmentation behavior is observed in both the target and projectile fragmentation regions for a central as well as for a minimum-bias sample. Comparisons with the fritiof model reveal that the picture of fragmenting strings successfully describes the observed data.
