中 微 子 混 合 角 (mixing angles)<br />

t = 0: | e >=a a | 1 >+b b | 2 ><br />

單 一 粒 子 : |a| 2 + |b| 2 = 1<br />

可 以 用 a = cos 12 , b = sin 12<br />

| 2 > | e ><br />

混 合 角<br />

| e > cos<br />

12 = 12 sin 12 | 1 ><br />

-sin 12 cos 12<br />

| 1 > | ><br />

| 2 ><br />

Mixing matrix<br />

-sin 12 cos 12<br />
