1. Introduction
The pursuit of a unified theoretical framework encompassing all fundamental interactions represents the paramount challenge in contemporary theoretical physics. Despite the remarkable successes of the Standard Model and general relativity, profound mysteries persist: the nature of dark matter and dark energy, the origin of cosmic acceleration, the hierarchy of fundamental constants, and the persistent Hubble tension between early and late universe measurements.
The Expanded Quantum String Theory with Gluonic Plasma (EQST-GP) model addresses these challenges through a novel synthesis of 11-dimensional M-theory, QCD dynamics, and loop quantum gravity. By identifying dark matter as a topologically stable gluonic plasma with negative Casimir energy and introducing a dynamic cosmological constant emerging from compactified dimensions, the framework achieves unprecedented unification while maintaining mathematical consistency and experimental verifiability.
1.1. Theoretical Foundations and Innovations
The EQST-GP model builds upon several key theoretical innovations:
11-Dimensional Compactification: Starting from the fundamental action of M-theory compactified on , the model naturally gives rise to Standard Model forces and particle content.
Gluonic Plasma Dark Matter: Dark matter is identified as Majorana gluons—topologically stable configurations arising from primordial gluonic plasma on M5-branes, with mass and interaction cross-section .
Dynamic Cosmological Constant: A negative energy density from M5-brane vacuum fluctuations dynamically modifies , naturally resolving the Hubble tension.
First-Principles Derivation: All fundamental constants and parameters are derived from geometric and quantum principles without arbitrary fitting parameters.
1.2. Experimental Verification and Predictions
The model’s predictive power is demonstrated through:
Precision matching of 25 fundamental constants within experimental uncertainties
Resolution of cosmological tensions (, ) while maintaining consistency with CMB and large-scale structure
Testable predictions for LISA gravitational wave observations ( at )
Novel signatures in high-energy particle collisions and dark matter detection experiments
2. Theoretical Framework: EQST-GP Fundamentals

8.3.1. Standard Model Extensions
While SUSY and composite Higgs models address hierarchy problems, they fail to provide:
First-principles derivation of fundamental constants
Natural dark matter candidate with correct relic density

EQST-GP achieves all these while maintaining better agreement with precision measurements.
8.3.2. String Theory Frameworks
Traditional string theory provides unification but suffers from:
Landscape problem with vacua
No unique prediction of Standard Model parameters
Inability to resolve Hubble tension
Lack of testable dark matter predictions
EQST-GP addresses these through the gluonic plasma mechanism and dynamic compactification.
