Cross sections for inelastic K+ϕscattering

Chinese Physics C 2023年第8期47卷 54-63页

作者：潘奕豪许晓明 Department of Physics Shanghai UniversityBaoshanShanghai 200444China

In the first Born approximation,we study the reactions Kφ→πK,ρK,πK*,and ρK*with quark-antiquark annihilation and *** amplitudes are derived with the development in the spherical harmonics of the relative-motion wave functions of two initial mesons and two final mesons so that parity is conserved and the total angular momentum of the final mesons equals that of the initial *** cross sections are calculated from the transition amplitudes that also contain mesonic quark-antiquark relative-motion wave functions and transition potentials for quark-antiquark annihilation and *** notable temperature dependence of the cross sections is *** cross sections for Kφ→ρK,Kφ→K*,and Kφ→ρK*may be of the millibarn scale,whereas the cross section for Kφ→πK is small.

In a previous paper [Commun. Theor. Phys., [arxiv：hep-ph/11081451]], guish poles of different dynamical origin, in unitarized amplitudes of ππ, K K system. that ＂A Breit-wigner resonance should exhibit two poles on different Riemann sheets axis when Nc = ∞＂. In this paper, we extend our previous work [Commun. Theor. to the ππ-KK=ηη three channel system. We reconfirm most of the predictions in our Phys., [arxiv：hep-ph/11081451]]. Especially the fo（980） is of KK molecule nature. 0 Breit-WJgner type. we proposed a method to distinThat is based on the observation which meet each other on the real phys,[arXiv：hep,ph/11081451]]*** work ： Theor. ther poles, including the σ,are of Breit-wigner type.

Pole Analysis on Unitarized SU(3) × SU(3) One Loop χPT Amplitudes

引用

Communications in Theoretical Physics 2012年第5期57卷 841-848页

作者：戴凌云王轩弓郑汉青 Department of Physics and State Key Laboratory of Nuclear Physics and Technology Peking University

We analyze ππ-KK and πη-Kk couple channel [1,1] matrix Padé amplitudes of SU(3) × SU(3) chiral perturbation *** fitting phase shift and inelasticity data,we determine pole positions in different channels (f 0 (980),a 0 (980),f 0 (600),K*0 (800),K*(892),ρ(770)) and trace their N c *** stress that a couple channel Breit-Wigner resonance should exhibit two poles on different Riemann sheets and meet each other on the real axis when N c=∞.Poles are hence classified using this criteria and we conclude that K*(892) and ρ(770) are unambiguous Breit-Wigner *** scalars the situation is much less *** find that f 0 (980) is a molecular state rather than a Breit-Wigner resonance,while a 0 (980),though behave oddly when varying N c,do maintain a twin pole structure.
