Inspire Record 220003 DOI 10.17182/hepdata.20236

The cross section for the production of π+π− or K+K− pairs in γγ interactions is measured for mππ between 1.7 and 3.5 GeV/c2 and for two intervals of γγ center-of-mass scattering angle. Results are compared with predictions of a QCD model.

Elastic Scattering at the {CERN} {SPS} Collider Up to a Four Momentum Transfer of 1.55-{GeV}**2

The UA4 collaboration Bozzo, M. ; Braccini, P.L. ; Carbonara, F. ; et al.
Phys.Lett.B 155 (1985) 197-202, 1985.
Inspire Record 213385 DOI 10.17182/hepdata.30410

Proton-antiproton elastic scattering was measured at the center-of-mass energy s =546 GeV in the four-momentum transfer range 0.45⩽−⩽1.55GeV 2 . The shape of the t -distribution is quite different from that observed in proton-proton scattering at the ISR. Rather than a dip-bump structure, a kink is present at − ≈0.9GeV 2 followed by a shoulder. The cross section at the second maximum is more than one order of magnitude higher than at the ISR.

Magnetic Form Factor of the Deuteron

Auffret, S. ; Cavedon, J.M. ; Clemens, J.C. ; et al.
Phys.Rev.Lett. 54 (1985) 649-652, 1985.
Inspire Record 214266 DOI 10.17182/hepdata.20337

We have measured the deuteron magnetic form factor B(q2) for values of the momentum transfer squared between 7 and 28 fm−2. The data are compared with relativistic and nonrelativistic predictions including meson-exchange-current contributions. Significant disagreement is found for large momentum transfers.

DECAY DISTRIBUTION OF HIGH TRANSVERSE MOMENTUM RHO MESONS

Inspire Record 221964 DOI 10.17182/hepdata.20301

The exclusive process π−p→ρ−p has been measured at 90° c.m. with an incident pion momentum of 9.9 GeV/c. We present data on the angular dependence of the decay ρ−→π−π0. We observe a strong azimuthal dependence in the decay in the c.m. helicity frame of the ρ. Such an azimuthal dependence is not compatible with SU(6) valence-quark perturbation calculations.

PRIMAKOFF PRODUCTION OF THE B+ (1235) MESON

Collick, B. ; Heppelmann, S. ; Joyce, T. ; et al.
Phys.Rev.Lett. 53 (1984) 2374-2377, 1984.
Inspire Record 215103 DOI 10.17182/hepdata.20414

We have measured the coherent nuclear production of π+ω systems at 202.5 GeV. This final state is dominated by the B+(1235) meson with a measured mass and full width of 1.271 ± 0.011 GeV and 0.232 ± 0.029 GeV, respectively. A radiative width of 230 ± 60 keV was extracted for the process B+(1235)→π+γ.

Comparison of $\bar{p} p$ and $p p$ Elastic Scattering With $0.6-{\rm GeV}^ < t < 2.1-{\rm GeV}^2$ at the {CERN} {ISR}

Erhan, S. ; Smith, A.M. ; Meritet, L. ; et al.
Phys.Lett.B 152 (1985) 131-134, 1985.
Inspire Record 206289 DOI 10.17182/hepdata.30431

p p and pp elastic scattering differential cross sections are presented for momentum transfer 0.6< t <2.1 GeV 2 and √ s = 53 GeV. Measurements were made in the same apparatus at the CERN Intersecting Storage Rings. The p p and pp results are in statistical agreement with one another over the entire t range, although the point at t =1.32 GeV 2 is 1.5 σ above the pp data. The p p points appear to have the same shape as the predictions of Donnachie and Landshoff but are significantly lower in magnitude for 0.9< t <1.5 GeV 2 .
