A study of the charge-exchange reaction $pp \to n\Delta^{++} (1232)$ at ISR energies
/ De Kerret, H (CERN) ; Aubert, Jean-Jacques (Annecy, LAPP) ; Bartl, Walter (Vienna, OAW) ; Brandt, A (Hamburg U., Inst. Exp. Phys. II) ; Broll, C (Annecy, LAPP) ; Coignet, G (Annecy, LAPP) ; Dibon, Heinz (Hamburg U., Inst. Exp. Phys. II) ; Eichinger, H (Vienna, OAW) ; Favier, Jean (Annecy, LAPP) ; Flügge, G (Hamburg U., Inst. Exp. Phys. II) et al.
A study is reported of the charge-exchange reaction pp to n Delta /sup ++/(1232) at the CERN intersecting storage rings (ISR) in the energy range square root s=23 to 53 GeV. From the analysis of the energy dependence of the total cross-section, of the differential cross- section d sigma /dt and of the decay angular distributions evidence is found that pion exchange is dominant up to square root s=23 GeV and that ( rho +A/sub 2/) exchange dominates the reaction for square root s>or=30 GeV, as described by simple Regge-pole models.

Study of hadronic events in pp collisions at square root s=62 GeV and comparison with hadronic events in e/sup +/e/sup -/ collisions
/ Breakstone, A ; Crawley, H B ; Doroba, K ; Drijard, Daniel ; Fabbri, F L ; Firestone, A ; Fischer, H G ; Frehse, H ; Geist, W ; Gokieli, R et al.
Presents an analysis of minimum bias events from proton-proton collisions at square root s=62 GeV in the CERN ISR. The authors remove the effects of both the leading protons and compare the B=0 mesonic residue of the events to the hadronic events of similar energy produced in e/sup +/e/sup -/collisions. [...]

A measurement of the cross section of the reaction $pp \rightarrow n\Delta^{++} (1232)$ at ISR energies
/ Kwak, N (CERN) ; Nagy, E (CERN) ; Regler, Meinhard (CERN) ; Schmidt-Parzefall, W (CERN) ; Schubert, Klaus R (CERN) ; Winter, Klaus (CERN) ; Brandt, A (Hamburg U., Inst. Exp. Phys. II) ; Dibon, Heinz (Hamburg U., Inst. Exp. Phys. II) ; Flügge, G (Hamburg U., Inst. Exp. Phys. II) ; Niebergall, F (Hamburg U., Inst. Exp. Phys. II) et al.
A measurement of the cross section of the charge-exchange reaction pp to Delta /sup ++/(1232)n at square root s=23, 31 and 45 GeV at the CERN-ISR is reported. The energy dependences continues to follow a power law p/sub lab//sup -n/ with n=1.94+or-0.03 indicating dominance of one-pion exchange at the lowest ISR energy; there is some evidence for deviation from this at the higher ISR energies.

The leading-baryon effect in Lambda /sub b//sup 0/ production in proton-proton interactions at square root s=62 GeV
/ Basile, M ; Bonvicini, G ; Cesare, P D ; Cifarelli, L ; Contin, A ; D'Ali, G ; Esposito, B ; Giusti, P ; Massam, Thomas ; Nania, R et al.
The measurement of the longitudinal-momentum production distribution of the 'beauty'-flavoured baryon Lambda /sub b//sup 0/, in the reaction pp to e/sup +/+ Lambda /sub b//sup 0/+anything at square root s=62 GeV, shows clear evidence for a leading-baryon effect in Lambda /sub b//sup 0/ production. A comparison with the data on Lambda /sub c //sup +/, Lambda /sub s//sup 0/ and Lambda /sub s//sup 0/ production is also given. [...]

Measurement of associated charm production in pp interactions at square root s=62 GeV
/ Basile, M ; Cifarelli, L ; Contin, A ; D'Ali, G ; Di Cesare, P ; Esposito, B ; Giusti, P ; Massam, Thomas ; Nania, R ; Palmonari, F et al.
The associated charm production has been studied in pp interactions at square root s=62 GeV. The comparison of the measured production cross- section and the e/sup -// pi /sup -/ ratio with various theoretical models and with existing inclusive e/ pi measurements allows one to conclude that the most likely interpretation of the associated production is in terms of a charmed baryon Lambda /sub c//sup +/ produced forward, plus the D meson produced centrally.
