Inclusive Charged Particle Production at the CERN anti-p p Collider

The UA2 collaboration Banner, M. ; Bloch, P. ; Bonaudi, F. ; et al.
Phys.Lett.B 122 (1983) 322-328, 1983.
Inspire Record 190969 DOI 10.17182/hepdata.30782

Transverse momentum distributions of pions, kaons and protons have been measured around 90° in the UA2 detector at the SPS p p collider, at a CM energy of 540 GeV. All the cross sections have increased by more than a factor of 2 over those measured at ISR energies and exhibit a flatter behaviour with respect to transverse momentum.

Charged Particle Multiplicity Distributions in Proton Anti-proton Collisions at 540-{GeV} Center-of-mass Energy

The UA1 collaboration Arnison, G. ; Astbury, A. ; Aubert, Bernard ; et al.
Phys.Lett.B 123 (1983) 108-114, 1983.
Inspire Record 182553 DOI 10.17182/hepdata.30779

Results on charged particle production in pp̄ collision at s 1 2 = 540 GeV are presented. The data were obtained at the CERN pp̄ collider using the UA1 detector, operated without magnetic field. The central particle density is 3.3 + - 0.2 per unit o pseudo-rapidity for non-diffractive events. KNO scaling of the multiplicity distributions withresults from ISR energies is observed.

Transverse Momentum Spectra for Charged Particles at the CERN Proton anti-Proton Collider

The UA1 collaboration Arnison, G. ; Astbury, A. ; Aubert, Bernard ; et al.
Phys.Lett.B 118 (1982) 167-172, 1982.
Inspire Record 179520 DOI 10.17182/hepdata.30855

We have measured transverse momentum spectra up to 10 GeV/ c for charged particles produced centrally in proton-antiproton collisions at 540 GeV in the centre of mass at the CERN collider. Our results are compared with data at ISR energies and with the predictions of a QCD model. The charged particle spectrum shows a clear dependence on charged track multiplicity.

Small Angle Elastic Scattering at the {CERN} Proton Anti-proton Collider

The UA1 collaboration Arnison, G. ; Astbury, A. ; Aubert, Bernard ; et al.
Phys.Lett.B 121 (1983) 77-82, 1983.
Inspire Record 180683 DOI 10.17182/hepdata.66558

3roton-antiproton elastic scattering at cm energy 540 GeV has been studied in the t range 0.14 ⩽ − t ⩽ 0.26 GeV 2 . The data is well fitted by an exponential form exp( bt ) with b = 13.3 ± 1.5 GeV −2 .

Measurement of the Proton - Anti-proton Elastic and Total Cross-section at a Center-of-mass Energy of 540-{GeV}

The UA4 collaboration Battiston, R. ; Bozzo, M. ; Braccini, P.L. ; et al.
Phys.Lett.B 117 (1982) 126-130, 1982.
Inspire Record 178898 DOI 10.17182/hepdata.30870

First results on the measurement of the elastic and total cross section at the CERN pp̄ Collider are presented. Combining the measurement of elastic scattering at low momentum transfer with the rate of inelastic interactions, a value of the total cross section of 66 mb with a 10% statistical error was obtained.

First Results on Low Momentum Transfer Elastic Scattering at the {CERN} Proton - Anti-proton Collider

The UA4 collaboration Battiston, R. ; Bozzo, M. ; Braccini, P.L. ; et al.
Phys.Lett.B 115 (1982) 333-337, 1982.
Inspire Record 178576 DOI 10.17182/hepdata.30890

Proton-antiproton elastic scattering at a centre-of-mass energy of 540 GeV was measured in the four-momentum transfer range 0.05 < − t < s .19 GeV 2 . The t -distribution can be fitted by the exponential exp( b ) with b =17.2±1.0 GeV −2 . This result indicates a rapid decrease of the width of the diffraction peak between ISR and Collider energies.

Inspire Record 178583 DOI 10.17182/hepdata.30880

Inclusive π 0 production has been measured at the CERN pp̄ collider, s =540 GeV , for 90° production angle and in a range of transverse momenta between 1.5 and 4.5 GeV/ c . The invariant production cross section is larger than that measured at s = 53 GeV for p-p collisions. The production of μ mesons aand of direct photons is also investigated.
