Quarkonium spin alignment in a vortical medium
- 1. Universidade Estadual de Campinas (UNICAMP)

Description
We use a potential model to investigate the phenomenology of quarkonium in a thermal rotating medium, where vorticity and spin density are not necessarily in equilibrium. We find that the quarkonium spin density matrix, as well as the binding energy and melting temperature, are sensitive to both the vorticity and the lack of equilibrium between vorticity and spin. This means that quarkonium spin alignment is a sensitive probe for vorticity and spin within the hydrodynamic phase. Information unequivocally pointing to spin-orbit nonequilibrium dynamics can be obtained from a combined study of quarkonium relative abundance and spin alignment, as well as experimentally obtainable off-diagonal density matrix elements.

Translated Description (Arabic)
نستخدم نموذجًا محتملًا للتحقيق في ظواهر الكواركونيوم في وسط دوار حراري، حيث لا تكون الدوامة وكثافة الدوران بالضرورة في حالة توازن. نجد أن مصفوفة كثافة دوران الكواركونيوم، وكذلك طاقة الربط ودرجة حرارة الانصهار، حساسة لكل من الدوامة وعدم التوازن بين الدوامة والدوامة. وهذا يعني أن محاذاة دوران الكواركونيوم هي مسبار حساس للدوامة والدوران داخل المرحلة الهيدروديناميكية. يمكن الحصول على المعلومات التي تشير بشكل لا لبس فيه إلى ديناميكيات عدم التوازن في المدار المغزلي من دراسة مشتركة للوفرة النسبية للكواركونيوم ومحاذاة الدوران، بالإضافة إلى عناصر مصفوفة الكثافة خارج القطر التي يمكن الحصول عليها تجريبيًا.Translated Description (English)
