Strong CP problem with 10(32) standard model copies

Area of Science:

• Particle Physics
• Cosmology
• Quantum Chromodynamics

Background:

• The hierarchy problem and the strong CP problem are major unsolved issues in fundamental physics.
• Existing solutions often require additional theoretical constructs like axions.
• Black hole physics imposes constraints on particle physics theories.

Purpose of the Study:

• To demonstrate that a recent solution to the hierarchy problem also addresses the strong CP problem.
• To explore the implications of black hole physics consistency for particle number and mass scales.
• To predict the value of the strong CP parameter (theta) and its experimental consequences.

Main Methods:

• Utilizing a recently proposed solution framework for the hierarchy problem.
• Applying consistency conditions from black hole physics.
• Calculating the expected value of the strong CP parameter (theta) within the proposed framework.

Main Results:

• The proposed solution simultaneously resolves both the hierarchy and strong CP problems without new particles like axions.
• Black hole physics consistency necessitates approximately 10^32 copies of the Standard Model to explain the TeV scale.
• The model predicts a strong CP parameter value of theta approximately 10^-9.

Conclusions:

• A unified solution to the hierarchy and strong CP problems is achievable within existing physics frameworks.
• The predicted value of theta strongly suggests enhanced sensitivity in neutron electric dipole moment experiments.
• This work provides a compelling theoretical motivation for precision measurements in particle physics.
