چکیده

هیپرهسته‌ها سیستم‌های مقیدی از نوکلئون‌ها و یک یا چند باریون شگفت (هیپرون) هستند که توسعه فیزیک آن‌ها به فهم بیشتر ساختار هسته و ویژگی‌های ذرات شگفت کمک می‌کند. یکی از اهداف مهم حوزه فیزیک هیپرهسته بررسی برهم‌کنش هیپرون- نوکلئون و هیپرون- هیپرون است که در این زمینه، بررسی ساختار هیپرهسته‌ها می‌تواند نقش اساسی در مطالعه این نوع برهم‌کنش‌ها بازی ‌کند. ما در این کار به بررسی برخی از ویژگی‌های مهم استاتیکی هیپرهسته‌های تک لامبدا (هسته‌های شامل یک باریون شگفت ) مانند انرژی بستگی و گشتاور مغناطیسی آنها می‌پردازیم. برای انجام محاسبات، با استفاده از معادله موج نسبیتی دیراک و با در نظر گرفتن پتانسیل اسپین-مدار، معادله تحلیلی انرژی بستگی و گشتاور مغناطیسی هیپرهسته‌ها را تعیین کرده و این مقادیر را برای برخی از هیپرهسته‌های سبک مانند و تعیین کرده و با سایر نتایج تئوری و برخی از داده‌های آزمایشگاهی مقایسه خواهیم کرد.

چکیده [English]

Hypernuclei are known as the bound states of nucleons and one or more strange baryons (hyperons) so the development of their physics helps to understand the structure of nuclei and the properties of strange baryons with more precision. One important goal in the field of hypernucleus physics is the study of the interaction of hyperon-nucleon and hyperon-hyperon. In this regard, the study of hypernuclei structure can play an essential role in understanding these types of interactions. In this work, we study some important static properties of single-lambda hypernuclei (nuclei containing a -baryon) such as their binding energy and magnetic moments. For our calculation, we use the Dirac relativistic wave equation considering a spin-orbit potential and determine the analytical equation of binding energy and magnetic moments. In the following, we will determine these quantities for some light hypernuclei such as  and . Our analytical results will be compared with other theoretical results as well as available experimental data.
