The geometric Standard Model Effective Field Theory

Abstract

A bstract We develop the geometric formulation of the Standard Model Effective Field Theory (SMEFT). Using this approach we derive all-orders results in the $$ \sqrt{2\left\langle {H}^{\dagger }H\right\rangle }/\Lambda $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt> <mml:mrow> <mml:mn>2</mml:mn> <mml:mfenced> <mml:mrow> <mml:msup> <mml:mi>H</mml:mi> <mml:mo>†</mml:mo> </mml:msup> <mml:mi>H</mml:mi> </mml:mrow> </mml:mfenced> </mml:mrow> </mml:msqrt> <mml:mo>/</mml:mo> <mml:mi>Λ</mml:mi> </mml:math> expansion relevant for studies of Electroweak Precision and Higgs data.
