TL;DR

This proceedings documents the 12th Workshop 'What Comes Beyond the Standard Models' held in Bled, Slovenia (2009), focusing on Norma Susana Mankoč Borštnik's 'approach unifying spin and charges' as a novel framework beyond the Standard Model. The approach predicts a fourth fermion family potentially observable at the LHC and a stable fifth family that could constitute dark matter, with discussions centering on its viability, Yukawa coupling properties, and responses to Witten's 'no go' theorem on fermion mass generation.

Motivation & Objective

• To explore theoretical frameworks that unify spin and gauge charges as a path beyond the Standard Model.
• To evaluate the viability of a new approach proposing that spin and charges are unified in a geometric or algebraic structure.
• To investigate whether the predicted fourth and fifth fermion families could explain LHC observations and dark matter properties.
• To address the challenge posed by Witten's 'no go' theorem on fermion masses in such theories.
• To assess the potential of the approach to resolve open questions in electroweak and strong interactions.

Proposed method

• The workshop employed extended, interactive discussion sessions over multiple days, with each session lasting several hours and structured in two-hour blocks.
• Presentations were followed by intense, real-time Q&A and debate, emphasizing conceptual exploration over formal paper delivery.
• The approach unifying spin and charges was presented as a non-Abelian gauge or geometric framework where spin and internal symmetries are unified.
• Theoretical predictions were derived from the algebraic structure of the unified symmetry group, leading to predictions of additional fermion families.
• Videoconferencing via the Virtual Institute for Astroparticle Physics (VIA) enabled remote participation and live transmission of lectures and discussions.
• The VIA system used Adobe Connect for high-quality recordings, real-time video/audio, chat, and shared whiteboard functionality for collaborative discussion.

Experimental results

Research questions

• RQ1 Is the approach unifying spin and charges a viable path beyond the Standard Model?
• RQ2 Can the predicted fourth fermion family be observed at the LHC?
• RQ3 Does the stable fifth fermion family provide a viable explanation for dark matter, including direct detection constraints?
• RQ4 How can the Yukawa couplings predicted by the theory be evaluated and tested?
• RQ5 Can the theory overcome Witten's 'no go' theorem that restricts fermion masses in similar models?

Key findings

• The approach unifying spin and charges predicts the existence of a fourth fermion family, which may be detectable at the Large Hadron Collider.
• The theory suggests a stable fifth fermion family that could constitute the dark matter, consistent with current astrophysical observations.
• The model proposes that the fifth family's baryons could explain the observed properties of dark matter, including results from direct detection experiments.
• Discussions highlighted that if direct detection experiments fail to confirm the fifth family, alternative theoretical paths must be explored.
• The videoconferencing system (VIA) proved effective for real-time, high-quality remote participation in scientific discussions, enabling global collaboration.
• The workshop demonstrated that extended, interactive dialogue is essential for evaluating speculative but conceptually rich theoretical frameworks.
