Physicists have long been trying to understand two major mysteries of the universe: why the Higgs boson has such a unique mass and how it interacts with other particles, known as the flavour puzzle; and why the universe is so stable at very small distances, known as the electroweak hierarchy problem. A new study proposes an innovative solution by combining two ideas: flavour non-universality and Higgs compositeness.
Flavour non-universality suggests that the fundamental forces of nature do not treat all particles equally. In this case, the strong force acts differently on light and heavy quarks, creating a hierarchy of masses. This idea is supported by recent observations in particle colliders.
Higgs compositeness proposes that the Higgs boson is made up of smaller particles called composite states, similar to how protons are composed of quarks and gluons. These composite states can interact with each other and with other particles, influencing the properties of the Higgs boson.
The new study combines these two ideas to create a model where the strong force acts non-universally on light and heavy quarks, leading to a hierarchical mass pattern. At the same time, the Higgs boson is composed of composite states that interact with each other and with other particles.
This model predicts distinct phenomenological signatures, such as non-standard effects from flavoured gauge bosons, modified Higgs couplings, and light top partners. These predictions can be tested at the Large Hadron Collider (LHC) and future e+e- colliders, providing a way to verify or rule out this new solution.
The study also highlights the importance of global symmetries in the strong sector, which are essential for generating realistic flavour hierarchies. The model requires a relatively large gauge coupling, gR, and a light top partner mass, Mρ, to satisfy experimental constraints.
Overall, this innovative approach offers a fresh perspective on the long-standing problems of flavour and electroweak stability, providing a new direction for researchers to explore.
