Measurements of $\pi^- p$ Elastic Scattering in the Coulomb Interference Region at High-energies

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.

Phys.Lett.B 77 (1978) 438-442, 1978.

Inspire Record 131449 DOI 10.17182/hepdata.27428

The differential cross section has been measured at 30, 50, 80, 100, 120 and 140 GeV/ c for 0.002 < | t | < 0.04 ( GeV / c ) 2 . The results show that the π − p real part goes from negative to positive values below 80 GeV/ c . The slope parameter in the t -region measured is significantly higher than what has been found − t = 0.2 (GeV/ c ) 2 .

Measurements of $\pi^- p$ Forward Elastic Scattering at High-energies

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.

Phys.Lett.B 109 (1982) 111, 1982.

Inspire Record 166767 DOI 10.17182/hepdata.31011

The differential cross section of π − p scattering has been measured in the energy region 100–345 GeV and in the t -range 0.002<| t |< 0.04 (GeV/ c ) 2 . The real part of the π − p scattering amplitude has been extracted from the data. The results show that the real part continues to increase with energy. The energy dependence of the slope parameter has also been determined. The shrinkage found expressed in terms of the slope of the pomeron trajectory is2 α ′ p =0.23±0.04 (GeV/ c ) −2 . This agrees with the energy dependence found at larger| t |-values.

Soft $\pi^- p$ and $p p$ Elastic Scattering in the Energy Range 30-{GeV} to 345-{GeV}

Burq, J.P. ; Chemarin, M. ; Chevallier, M. ; et al.

Nucl.Phys.B 217 (1983) 285-335, 1983.

Inspire Record 182455 DOI 10.17182/hepdata.7556

Differential cross sections for π − p and pp elastic scattering have been measured at incident momenta ranging from 30 to 345 GeV and in the t range 0.002 (GeV/ c ) 2 ⩽ | t | ⩽ 0.04 (GeV/ c ) 2 . From the analysis of the data, the ratio ϱ ( t = 0) of the real to the imaginary parts of the forward scattering amplitude was determined together with the logarithmic slope b of the diffraction cone.

Phys.Rev.Lett. 60 (1988) 1118-1121, 1988.

Inspire Record 264273 DOI 10.17182/hepdata.3063

Cross sections or upper limits are reported for 12 meson-baryon and two baryon-baryon reactions for an incident momentum of 9.9 GeV/c, near 90° c.m.: π±p→pπ±,pp±,π+°±,K+Σ±, (Λ0/Σ0)K0; K±p→pK±; p±p→pp. By studying the flavor dependence of the different reactions, we have been able to isolate the quark-interchange mechanism as dominant over gluon exchange and quark-antiquark annihilation.

Small-Angle pi- p Elastic Scattering Measurements

Phys.Lett.B 56 (1975) 391-394, 1975.

Inspire Record 90800 DOI 10.17182/hepdata.27866

We have measured small angle elastic pion-proton scattering in 40 and 50 GeV c π − beams at Serpukhov. Analysis of the data in the Coulomb interference region yields a value for the ratio of the real to the imaginary part of the strong amplitude, ϱ (0)=−0.074 ± 0.033 at 40 GeV/ c and ϱ (0)=−0.006 ±0.026 at 50 GeV/ c
