Neetika Sharma, Harleen Dahiya

摘要:

本文用手征组分夸克模型(\chiCQM)和广义参数化(GP)方法计算了自旋为3/2^+的十重态重子和自旋为3/2^+的\to 1/2^+跃迁的四极矩.这样一个模型的影响进行了详细的研究对称性破缺和GP参数有关的两个和三个夸克的贡献的影响。结果表明,\chiCQM能成功地定量和定性地描述四极矩。

英文摘要:

The chiral constituent quark model (\chiCQM) with general parameterization (GP) method has been formulated to calculate the quadrupole moments of the spin 3/2^+ decuplet baryons and spin 3/2^+ \to 1/2^+ transitions. The implications of such a model have been investigated in detail for the effects of symmetry breaking and GP parameters pertaining to the two- and three-quark contributions. It is found that the \chiCQM is successful in giving a quantitative and qualitative description of the quadrupole moments.
