概要
- 論文の詳細を見る
Effective Lagrangian including technimesons is constructed for a realistic one-family Technicolor model without exact custodial symmetry. Tree level contributions to oblique correction parameters S and U due to spin l technimesons are computed with the effective Lagrangian. An isospin breaking term which is associated with technilepton vector mesons gives a negative contribution to the electroweak radiative correction parameter S due to mixing between I=0 and I=1 vector mesons. U receives non-zero contribution from exotic left-handed charged vector mesons and its sign can be both negative and positive.
