Interference between $K_L \to \pi^+ \pi^-$ and $K_S \to \pi^+ \pi^-$ behind a copper regenerator

Faissner, H. ; Foeth, H. ; Staude, A. ; et al.

Inspire Record 56677 DOI 10.17182/hepdata.28905

The interference between K L → π + π - and K S → π + π - behind a copper regenerator has been observed in a high statistics experiment. The modulus and the argument of the complex ratio ϱ ( p )/ η +- , where ϱ ( p ) is the regeneration amplitude and η +- = A ( K L → π + π - )/ A (K S → π + π - ) has been measured over the momentum interval from 2.0 GeV/ c to 6.0 GeV/ c . The phase of η +- as deduced from this measurement and from the optical model value of arg [ ϱ ( p )] is 49.3° ± 6.8°. The K L K S mass difference has been found to be Δm/ h ̵ = (0.555 ± 0.020) × 10 10 sec −1 .

Neutron-proton elastic scattering in the forward direction between 4 and 16 gev

Engler, J. ; Horn, K. ; Konig, J. ; et al.

Inspire Record 56753 DOI 10.17182/hepdata.28979

The differential cross-section for the elastic neutron-proton-scattering has been measured for neutron energies between 4 and 16 GeV and | t | from 0.3 to 1.3 (GeV/ c ) 2 . The results can be fitted by exp( A + Bt ), where B increases slightly with energy indicating shrinkage. The values of B for n−p scattering are in good agreement with the corresponding data for p−p scattering.

Results are presented from an experiment in which high-energy deuterons, produced by proton-proton interactions at 21.1 GeV/ c incident momentum, were detected over a range of angles from 12.5 mrad to 60 mrad in the laboratory system. From the momentum spectra of the deuterons, the final states D + π + and D + ϱ + have been identified. The angular distribution for these reactions are presented and compared with previous data at lower energies.
