1) general hypercharge and general spinor
广义旋量和超荷
2) hypercharge-spinor transformation
超荷-旋量变换
1.
The transformation between I3F,C3F,t3F and YF of three generation quarks and leptons of Fermi type follows the hypercharge-spinor transformation,and so does that between I′3B,C′3B,t′3B and Y′B of their three generation supersymmetry companions,antiquarks and antileptons of Bose type.
三代费米型夸克、轻子的I3F,C3F,t3F,YF间及它们的超对称伴子三代玻色型反夸克、反轻子的I′3B,C′3B,t′3B,Y′B间均满足超荷-旋量变换。
3) (Generalized) Ultrametric Space
广义超度量空间
4) generalized ultrametric matrix
广义超度量矩阵
1.
It is proved that when A is a nonsingular generalized ultrametric matrix,then the Hadamard product Ao A~T is also a generalized ultrametric matrix and its inverse is an M- matrix.
本文研究了广义超度量矩阵的封闭性质。
5) generalized load
广义载荷
6) generalized hypertree
广义超树
补充资料:超荷
| 超荷 hypercharge 描述强子内部性质的一种相加性量子数,记为Y。在粒子物理某些场合,粒子的重子数和奇异数以和的形式出现,反映两者之和具有内在的确定意义,因此定义粒子的重子数和奇异数之和为超荷,有时用它来代替奇异数。与奇异数类似,在强作用和电磁作用过程中超荷守恒,在弱作用过程中超荷可以不守恒,ΔY=0,±1。强子的超荷通过盖耳曼-西岛关系同它的电荷Q及同位旋第三分量I相联系,Q=I3+Y/2。盖耳曼-西岛关系在强子分类中曾起重要作用。 |
