Higgs Boson Emerging from the Dark.

Area of Science:

• Particle Physics
• Cosmology
• Dark Matter Physics

Background:

• The origin of dark matter remains a significant unsolved problem in physics.
• Existing dark matter production mechanisms often rely on thermal relics or specific particle interactions.
• Vacuum misalignment offers a compelling alternative framework for generating relic abundances.

Purpose of the Study:

• To propose and analyze a new nonthermal mechanism for dark matter production.
• To explore the implications of vacuum misalignment in generating dark matter and charge asymmetry.
• To demonstrate the viability of this mechanism within a composite Higgs model.

Main Methods:

• Theoretical modeling of dark matter production via vacuum misalignment.
• Analysis of charge asymmetry generation at high temperatures and subsequent breaking of U(1)_X.
• Application and validation of the mechanism within a composite Higgs template model.

Main Results:

• A novel nonthermal dark matter production mechanism based on vacuum misalignment is established.
• The mechanism naturally generates a global X-charge asymmetry, with a fraction stored in stable dark matter.
• A light pseudo-scalar particle (η) is predicted, with potential observable consequences.

Conclusions:

• Vacuum misalignment provides a viable and versatile mechanism for nonthermal dark matter production.
• The predicted pseudo-scalar particle has significant implications for cosmology, supernovae, and particle decays.
• This mechanism offers a new avenue for exploring dark matter origins in various theoretical models.
