用软辐射探测重共振的规范含量

Probing the Gauge Content of Heavy Resonances with Soft Radiation

Ilmo Sung

摘要:

能量流的使用被研究作为一种诊断工具,用于确定新共振的颜色SU(3)表示。结果表明,软胶子辐射进入快度隙的模式依赖于硬散射中的色流,反映了新物理的规范含量。本文引入了快度隙事件的大质量软反常维数矩阵,用以解析地描述重夸克对产生中的软胶子发射。间隙分数用于量化进入间隙区域的软辐射的量。在一般情况下,结果表明,辐射是更大的单重态共振比八重态。特别是,它被发现的数量差异是相当明显的自旋-1共振,取决于在新的部门的规范内容。

英文摘要:

The use of energy flow is investigated as a diagnostic tool for determining the color SU(3) representation of new resonances. It is found that the pattern of soft gluon radiation into a rapidity gap depends on color flow in the hard scattering, and reflects the gauge content of new physics. The massive soft anomalous dimension matrix for rapidity gap events is introduced for describing soft gluon emission analytically in heavy quark pair production. A gap fraction is used for quantifying the amount of soft radiation into the gap region. In general, the results illustrate that radiation is greater for a singlet resonance than for an octet. Especially, it is found that the quantitative difference is quite distinguishable for spin-1 resonances, depending on the gauge content in the new sector.
