چکیده

در کار حاضر رد پای تشدید \Lambda(1405) در طیف تکانه ترایتون و پایون ناشی از جذب تشدیدی کائون متوقف شده بر روی ^4He ، با استفاده از رهیافت کانال‌های جفت‌شده محاسبه و مورد بررسی قرار گرفته است. به‌همین منظور برای توصیف برهم‌کنش کائون‌‌-نوکلئون از پتانسیل‌های مختلف پدیده‌شناختی و کایرالی چون آکائیشی‌-یامازاکی، هیدو‌-‌وایز، کک تک‌- و دو-قطبی و سیدارتا تک‌- و دو-قطبی استفاده شده است. هم‌چنین با محاسبه طیف‌های انحراف تکانه ترایتون و پایون نشان داده‌ایم که اثرات تشدید \Lambda(1405) به‌وضوح، به-صورت قله‌ایی در طیف‌های انحراف قابل مشاهده است و چنین طیف‌هایی می‌توانند اطلاعات مفیدی در ارتباط با برهم‌کنش K\bar N و تشدید \Lambda(1405) را نتیجه دهند.

چکیده English

In present work, the trace of \Lambda(1405) resonance in the triton and pion momentum spectrum due to resonant absorption of stopped kaon on ^4He have been calculated and investigated using the coupled-channel approach. For this purpose, different phenomenological and chiral kaon-nucleon potentials such as Akaishi-Yamazaki, Hyodo-Wise and one and two pole KEK and one and two pole SIDDHARTA have been used. Also, by calculation of the pion and triton deviation momentum spectra, we have shown that the effect of \Lambda(1405) resonance is clearly visible in the spectra and such spectra can yield useful information regarding K\bar N interaction and \Lambda(1405) resonance.
