NLO启发有效拉格朗日希格斯物理

NLO Inspired Effective Lagrangians for Higgs Physics

Giampiero Passarino

摘要:

今年秋末或最迟明年初,LHC应该会有2-3倍于目前数据的结果,这可能会给光窄共振耦合的第一个线索。测量偏离标准模型的策略可以基于使用“完整”标准模型,包括所有可用的QCD和电弱高阶校正,并补充它与d= 6本地运营商。假设它们的Wilson系数足够小,可以在首阶处理。本地运营商与BSM拉格朗日函数的连接的例子,以及讨论拉格朗日函数与/不解耦的重自由度。根据内部一致性对整个战略进行了严格审查。

英文摘要:

Either late autumn this year or latest early next year LHC should have results with 2-3 times the current data which migth give first clues on the couplings of the light narrow resonance. A strategy for measuring deviations from the Standard Model can be based on using the "full" Standard Model, including all available QCD and electroweak higher-order corrections, and supplement it with d= 6 local operators. Their Wilson coefficients are assumed to be small enough that they can be treated at leading order. Examples of the connection of local operators with BSM Lagrangians are presented as well as a discussion of Lagrangians with/without decoupling of heavy degrees of freedom. The whole strategy is critically reviewed in the light of internal consistency.
