TL;DR

This paper presents the proceedings of the 13th Bled Workshop on 'What Comes Beyond the Standard Models,' focusing on the spin-charge-family theory as a unified framework unifying spin and gauge charges, predicting three generations of fermions and a stable fifth family that may constitute dark matter. The theory addresses open questions in particle physics and cosmology, including fermion mass hierarchies, matter-antimatter asymmetry, and the role of complex actions in quantum field theory, with implications for LHC dark matter searches and direct detection experiments.

Motivation & Objective

• To explore theoretical frameworks that unify spin and gauge charges, addressing unresolved issues in the Standard Model of particle physics.
• To investigate the origin of fermion families and the possibility of a stable fifth family that could explain dark matter.
• To analyze the role of complex actions in quantum field theory and their potential to resolve issues in loop diagrams and interpretation of quantum mechanics.
• To examine the behavior of heavy fifth-family particles during electroweak and color phase transitions in the early universe.
• To assess the viability of the spin-charge-family theory in explaining direct dark matter detection signals and LHC phenomenology.

Proposed method

• Employing the spin-charge-family theory, which unifies spin and gauge charges in a higher-dimensional spacetime framework with additional internal symmetries.
• Using a complex action formalism to regulate loop diagrams and explore non-perturbative effects in quantum field theory.
• Applying the De Broglie-Bohm pilot-wave approach to interpret quantum mechanics within the complex action framework.
• Analyzing phase transitions in the early universe, particularly electroweak and color transitions, to determine the behavior of heavy fifth-family fermions.
• Modeling composite dark matter candidates as neutral baryons and neutrinos from the fifth family, including their interactions and detection prospects.
• Conducting virtual interactive discussions (VIA) via videoconferencing to include remote participants in real-time scientific exchange, integrating global expertise in astroparticle physics.

Experimental results

Research questions

• RQ1 To what extent can the spin-charge-family theory resolve open questions in both the elementary particle and cosmological Standard Models?
• RQ2 Can the fifth family's neutral baryons and neutrinos explain the observed properties of dark matter, including direct detection data?
• RQ3 How do fifth-family fermions behave during electroweak and color phase transitions in the early universe?
• RQ4 What triggers the fermion-antifermion asymmetry in the spin-charge-family theory, and how do two stable families influence the matter-antimatter asymmetry?
• RQ5 Can the coherent contribution of quantum corrections beyond the tree level explain the observed mass hierarchies and mixing patterns among the three known families?

Key findings

• The spin-charge-family theory predicts the existence of a fourth fermion family, which may be observed in future experiments, and a stable fifth family that could constitute the dark matter.
• Fifth-family neutral baryons and neutrinos are proposed as viable dark matter candidates, consistent with current direct detection constraints and experimental signals.
• The theory suggests that the electroweak phase transition occurs at approximately 1 GeV, with implications for the behavior of heavy fifth-family quarks and leptons.
• The complex action formalism is explored as a potential regulator for loop diagrams and as a tool to improve the interpretation of quantum mechanics via the De Broglie-Bohm approach.
• Virtual interactive sessions (VIA) enabled real-time, inclusive scientific discussions across global institutions, integrating remote participants from CERN, Moscow, Liege, Marburg, and the USA.
• Discussions revealed that composite dark matter scenarios, including neutral nuclei from the fifth family, may resolve discrepancies in direct dark matter search experiments.
