Hyperon distribution and correlation in (K−,K+) reactions

Hyperon Distribution and Correlation in (K−, K+) Reactions

We analyze the hyperon momentum distribution and correlation in (K−, K) reactions on C and Be targets. Both of K and Λ momentum distributions are well reproduced with the the IntraNuclear Cascade model followed by the statistical evaporation of Λ from hyperon compound nuclei. In the momentum correlation analysis of ΛΛ based on the model source functions, it is shown that strongly attractive ΛΛ ...

Hypernuclear Physics Polarization Effects in Exclusive Hyperon Production Reactions

coordination of protective schemes in distribution and subtransmission systems including distributed generation

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...

Exchange Currents in Radiative Hyperon Decays and Hyperon Charge Radii

Radiative decays of decuplet hyperons and octet hyperon charge radii are evaluated in a chiral constituent quark model emphasizing the role of exchange currents. Exchange currents largely cancel for the M1 decay amplitudes, while they dominate the E2 amplitude. Due to the pseudoscalar meson cloud the charge radii of Σ and Ξ are almost as large as the proton radius, in agreement with recent expe...
