# Impact of Yukawa-like dimension-5 operators on the Georgi-Machacek model

## TL;DR

This paper examines how Yukawa-like dimension-5 operators influence the charged Higgs sector in the Georgi-Machacek model, affecting constraints from B-meson decays, mixing, and Zbb measurements.

## Contribution

It introduces the effects of dimension-5 operators into the Georgi-Machacek model, showing significant changes in the bounds on charged Higgs masses and triplet VEVs.

## Key findings

- Dimension-5 operators substantially alter charged Higgs mass limits.
- Constraints from B-meson decays and Zbb are affected.
- Vacuum expectation values of triplets are modified.

## Abstract

We study the effects of including Yukawa-like dimension-5 operators in the Georgi-Machacek model where the Standard Model is augmented with triplet scalars. We focus only on the charged Higgs sector and investigate the constraints arising from radiative B-meson decays, neutral B-meson mixing and precision measurement of Zbb vertex. We observe that the inclusion of the dimension-5 operators causes substantial alteration of the limits on the charged Higgs masses and the vacuum expectation value of the triplets, derived otherwise using only the dimension-4 operators.
