Bottom quark electroweak dipole moments at a high-energy μ−collider
- 1Universitá di Pisa and INFN, Sezione di Pisa
Abstract
A bstract : We study the sensitivity of a high-energy μ –collider with center of mass energy in the multi–TeV range in testing electroweak dipole interactions of the b -quark. We parametrize the relevant deformations in the language of the Standard Model effective field theory, where the dominant modifications arise at the d = 6 level. We analyse μ+μ−→ bb̅ μ + μ − → b b ¯ and μ+μ−→ bb̅h μ + μ − → b b ¯ h scatterings, performing a study at the level of a fast detector simulation. Owing the chiral structure of the dipole interaction, the study of the μ+μ−→ bb̅h μ + μ − → b b ¯ h process allows to enforce the stronger bounds on the Wilson coefficients of the d = 6 operators. The limits that can be obtained surpass present and future bounds from EW precision measurements also improving upon the ones arising from the measurement of the ∆ F = 1 transitions B → X s γ .
