“…The contribution of the peripheral sample (cos0y*<-0.6) is ~187 jub. This leads to a Y*K*p coupling constant g 2 /4:w=40-50, which is a factor of ~ 2 larger than expected 143 on the basis of the N*K*p coupling with SU% coefficients. The production angular distribution of the F 0 *(1405) shown in Fig.…”

K~-p interactions at 2.24 BeV/c were studied in several exposures of the Brookhavan National Laboratory 20-in. hydrogen bubble chamber at the alternating-gradient synchrotron. We give an account of all aspects of the experiment, including: experimental procedures, scanning and measuring techniques, data-reduction methods, and experimental results and their consistency with the current theories of strong and weak inter actions. The experimental results are grouped as follows: meson and baryon resonance spectroscopy; other two-body and three-body reactions; the S hyperon; and total cross sections. For completeness, we include information published elsewhere but add important details not previously given. In addition, we report a considerable range of new results.

Double-Octet Regge-Pole Model with Exchange Degeneracy for Charge- and Hypercharge-Exchange Reactions

A model for pseudoscalar-meson-baryon and pseudoscalar-meson-baryon-resonance hpyercharge-and charge-exchange reactions at high energies is proposed, based on an octet of pairs of opposite-signature Regge poles. The model may be considered as an extension of the charge-exchange reaction model for K~p used by Phillips and Rarita, incorporating SU(3) symmetry and exchange degeneracy. In addition, the universality hypothesis is employed to extend the model to B* production. The model thus extended contains only a few parameters (essentially only 2) and agrees with all available high-energy, small-momentumtransfer data on these reactions. The energy dependences (involving no free parameters) are very good; the universality hypothesis is satisfied within narrow experimental bounds, and S U (3)-symmetric normalizations are within a factor of 2 for most cross sections at high energy.

“…In cases in which definite calculations have been made, agreement between theoretical predictions and experimental data is reasonable. 22 The present work is carried out in order to investigate the production mechanisms of double resonance production in the reactions w + +p -*N*+p and 7r ++£__ > jY r *+w.…”

“…5 - 14,15 But the production distributions were in general more "peripheral" (forward or backward peaked) than predicted by unmodified singleparticle exchange models, and a strongly momentumtransfer-dependent form factor was needed to make the theoretical curves fit the experimental data. In order to avoid using such an ad hoc form factor, several authors [16][17][18][19][20][21][22] have proposed single-particle-exchange models which take into consideration the effects due to absorption in the initial and final state of reaction. In this way low partial waves are absorbed by other competing open channels, and thus produce a desired peaking in the production angular distribution.…”

Double Resonance Production by 2.77-BeV/cπ+Mesons on Hydrogen

Reactions *•++£ -> w++Tr + +TT-{-p, ir + +p -> ir + -f*-+ -f Tr-+p+ir Q and ir + +p -> 7r + +x + +7r + +7r-+w were studied at an incident w + momentum of 2.77 BeV/c. The first reaction is dominated by a quasi-twobody intermediate state p+N*. The decay distributions of p and N* are consistent with the predictions of the single-pion-exchange model. The p° decay distributions show the well-known asymmetry, which may be attributed to an interference with a T=0 even-spin background. The second reaction is dominated by a quasi-two-body intermediate state w-f-iV*. The decay distributions of o> and N* are not consistent with the unmodified p-exchange model, but could be made to be consistent by including the absorptive effects in the input and output channels. The last reaction shows no prominent resonance production.
