The K¯N Interaction in Higher Partial Waves

نویسندگان

چکیده

We present a chiral K¯N interaction model that has been developed and optimized in order to account for the experimental data of inelastic reaction channels open at higher energies. In particular, we study effect partial waves, which originate directly from Lagrangian, as they could supersede role high-spin resonances employed earlier phenomenological models describe meson-baryon cross sections 2 GeV region. detailed derivation wave amplitudes emerge SU(3) Lagrangian up d-waves next-to-leading expansion. implement nonperturbative unitarization coupled optimize parameters large pool relevant energy range where these new contributions are expected be important. The obtained results encouraging. They indicate ability waves extend description scattering energies structures cross-sections cannot accommodated by theoretical limited s-waves.

Can the effective string see higher partial waves ?

The semi-classical cross-sections for arbitrary partial waves of ordinary scalars to fall into certain five-dimensional black holes have a form that seems capable of explanation in terms of the effective string model. An attempt is made to understand these cross-sections in detail in terms of the effective string, and two stumbling blocks are noted. First, a peculiar value of the effective stri...

Higher Partial Waves in Pp ! Ppp near Threshold

Exclusive measurements of the production of-mesons in the pp ! ppp reaction have been carried out at excess energies of 16 and 37 MeV above threshold. The deviations from phase space are dominated by the proton-proton nal state interaction and this innuences particularly the energy distribution of the meson. However, evidence is also presented at the higher energy for the existence of an anisot...

Effect of Fertilizer and Soil Compactness Interaction on N, P and K in the Culture of Lawn

Under favorable soil conditions such as existence of easily destructible organic compounds, balanced heat and moisture, adequate ventilation and abundant nutrients, organic materials are mineralized. Once mineralizing occurs, mineral elements like P, S, Ca, Mg, K and other cations are released. A related study was conducted to determine the effect of seven organic fertilizers (Leaf Mold (LM), R...
