The inclusive production of charmed baryonsΛc+ by 40–70 GeV neutrons on carbon has been observed. The decays$\Lambda _c^ + \to \bar K^0 p\pi ^ + \pi ^ -$ (130 ± 18 events) andΛc+→Λ0π+π+π− (57±14 events) have been detected. The mean value ofΛc+ mass is (2,268±6) MeV/c2. The invariant cross section forX>0.5 is described byE·d3σ/dp3∝ exp(−)bPT·(1−X)n withb=(2.5±0.6) (GeV/c)−1 andn=(1.5±0.5).

Invariant cross sections for hadron production (π±,K±,p and$\bar p$) by protons off C, Al, Cu, Sn and Pb nuclei have been measured at 70 GeV for theP∧ range from 1 up to 4.65 GeV/c. TheA-dependence of the invariant cross section is not described by the exponentialAα(P∧), which points to the presence of secondary hadron absorption in nuclei.

Results on the study of D(1285)→K + K − π 0 -decay are presented. The K + K − effective mass spectrum is measured with statistics which are by an order of magnitude higher than in the previous data. From the analysis of the differential spectrum d N d M KK (in the framework of the δ-dominance model) the δ-meson effective width is Γ δ >180MeV/ c 2 at √ s =1 GeV/ c 2 , which means a strong coupling of the δ-meson with hadrons.

Production of Charged Hadron Pairs With Large Symmetric Transverse Momenta in $p p$ Collisions at 70-{GeV}

Abramov, V.V. ; Baldin, B.Yu. ; Buzulutskov, A.F. ; et al.

Nucl.Phys.B 245 (1984) 1-16, 1984.

Inspire Record 197233 DOI 10.17182/hepdata.41020

We measured the cross sections of hadron pair production (π, K, p) with symmetric momenta produced back-to-back in the c.m.s. in pp collisions in the range 0.45 ⩽ P T ⩽ 1.99 GeV/ c . Particle correlations showing dependence on quantum numbers and transverse momentum are presented. The data are discussed in the framework of parton models.
