K+ p Elastic Scattering at 32-GeV/c

The FRENCH-SOVIET-CERN collaboration Granet, P. ; Loret, M. ; Mosca, L. ; et al.
Phys.Lett.B 62 (1976) 350-352, 1976.
Inspire Record 114035 DOI 10.17182/hepdata.27668

Elastic scattering of 32.1 GeV/ c K + on protons has been measured in a bubble chamber experiment. Results are presented in the momentum transfer interval 0.06–1.40 GeV 2 and compared with data at different energies. An effective Regge trajectory is calculated using K + p elastic data from 10 to 175 GeV/ c .

A measurement of the total $pp$ cross section at the LHC at $\sqrt{s}=7$ TeV is presented. In a special run with high-$\beta^{\star}$ beam optics, an integrated luminosity of 80 $\mu$b$^{-1}$ was accumulated in order to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable $t$. The measurement is performed with the ALFA sub-detector of ATLAS. Using a fit to the differential elastic cross section in the $|t|$ range from 0.01 GeV$^2$ to 0.1 GeV$^2$ to extrapolate to $|t|\rightarrow 0$, the total cross section, $\sigma_{\mathrm{tot}}(pp\rightarrow X)$, is measured via the optical theorem to be: $$\sigma_{\mathrm{tot}}(pp\rightarrow X) = 95.35 \; \pm 0.38 \; ({\mbox{stat.}}) \pm 1.25 \; ({\mbox{exp.}}) \pm 0.37 \; (\mbox{extr.}) \; \mbox{mb},$$ where the first error is statistical, the second accounts for all experimental systematic uncertainties and the last is related to uncertainties in the extrapolation to $|t|\rightarrow 0$. In addition, the slope of the elastic cross section at small $|t|$ is determined to be $B = 19.73 \pm 0.14 \; ({\mbox{stat.}}) \pm 0.26 \; ({\mbox{syst.}}) \; \mbox{GeV}^{-2}$.

Inspire Record 239695 DOI 10.17182/hepdata.38007

A random search for solutions of the phase-shift analysis of pp scattering at 970 MeV is carried out. Solutions were selected according to the correct position of the zero of trajectory I of the Barrelet amplitude f1 in addition to the statistical criteria. Two pairs of solutions with similar phase shifts are found as a result. Two of these solutions have been found before

Study of Elastic $\pi^+ p$, $K^+ p$ and $p p$ Scattering at 250-{GeV}/$c$

Phys.Lett.B 186 (1987) 223-226, 1987.
Inspire Record 246909 DOI 10.17182/hepdata.40833

Results are presented on π + p and K + p elastic scattering at 250 GeV/ c , the highest momentum so far reached for positive meson beams. The experiment (NA22) was performed with the european hybrid spectrometer. The π + p elastic cross section stays constant with energy while the K + p cross section increases.
