كان هناك تقدما مهما في القطاع الثقيل للباريونات في السنوات الأخيرة. نحن ندرس التحللات القوية للجيل الثاني الصوتي، والجيل الثالث الصوتي، والجيل الرابع الصوتي والجيل المشتت الشحصي باستخدام نموذج $^3P_0$. بعد مقارنة النمط المحسوب للتحللات والعرض الإجمالي مع البيانات المتوفرة، نناقش الهيكل الداخلي المحتمل والأرقام الكمية لهذه الباريونات المحظوظة المذهلة مؤخرا.
There has been important experimental progress in the sector of heavy baryons in the past several years. We study the strong decays of the S-wave, P-wave, D-wave and radially excited charmed baryons using the $^3P_0$ model. After comparing the calculated decay pattern and total width with the available data, we discuss the possible internal structure and quantum numbers of those charmed baryons observed recently.
The hadronic two-body weak decays of the doubly charmed baryons $Xi_{cc}^{++}, Xi_{cc}^+$ and $Omega_{cc}^+$ are studied in this work. To estimate the nonfactorizable contributions, we work in the pole model for the $P$-wave amplitudes and current al
Doubly Cabibbo-suppressed (DCS) nonleptonic weak decays of antitriplet charmed baryons are studied systematically in this work. The factorizable and nonfactorizable contributions can be classified explicitly in the topological-diagram approach and tr
We have investigated the electromagnetic decays of the antitriplet and sextet charmed baryon systems with $J^P= frac{1}{2}^+, frac{3}{2}^+$ in the framework of the heavy baryon chiral perturbation theory. We first construct the chiral Lagrangians at
We systematically study the semileptonic decays of ${bf B_c} to {bf B_n}ell^+ u_{ell}$ in the light-front constituent quark model, where ${bf B_c}$ represent the anti-triplet charmed baryons of $(Xi_c^0,Xi_c^+,Lambda_c^+)$ and ${bf B_n}$ correspond
In this work we study the radiative decay of dynamically generated $J^P=oh^-$ charm baryons into the ground state $J^P=oh^+$ baryons. Since different theoretical interpretations of these baryonic resonances, and in particular of the $Lambda_c(2595)$,
