一种修正的自然度原理及其实验检验

A modified naturalness principle and its experimental tests

Marco Farina, Duccio Pappadopulo, Alessandro Strumia

摘要:

受LHC结果的启发,我们通过忽略不可计算的幂次发散来修改通常的自然性标准。标准模型满足其参数测量值的修正准则(“有限自然”)。由观测(暗物质,中微子质量,强CP问题,真空不稳定性,通货膨胀)激发的SM扩展满足有限的自然在其参数空间的特殊范围内,这往往意味着低于几个TeV的新粒子。有限自然界比通常的自然界弱,因为任何新的粒子与SM规范相互作用给出了一个有限的贡献,希格斯质量在两个圈的顺序。

英文摘要:

Motivated by LHC results, we modify the usual criterion for naturalness by ignoring the uncomputable power divergences. The Standard Model satisfies the modified criterion ('finite naturalness') for the measured values of its parameters. Extensions of the SM motivated by observations (Dark Matter, neutrino masses, the strong CP problem, vacuum instability, inflation) satisfy finite naturalness in special ranges of their parameter spaces which often imply new particles below a few TeV. Finite naturalness bounds are weaker than usual naturalness bounds because any new particle with SM gauge interactions gives a finite contribution to the Higgs mass at two loop order.
