Beyond-Standard-Model Tensor Interaction and Hadron Phenomenology

Area of Science:

• Particle Physics
• Quantum Chromodynamics
• Hadron Phenomenology

Background:

• The Standard Model (SM) of particle physics describes fundamental particles and forces but may not be complete.
• Exploring physics beyond the Standard Model (BSM) is crucial for a deeper understanding of the universe.
• Tensor interactions are a potential BSM phenomenon that requires stringent constraints.

Purpose of the Study:

• To investigate the impact of recent advancements in hadron phenomenology on constraining BSM tensor interactions.
• To identify novel observables that can improve the precision of these constraints.
• To establish a connection between experimental measurements and theoretical calculations in lattice QCD.

Main Methods:

• Analysis of recent developments in hadron phenomenology.
• Inclusion of novel observables such as chiral-odd generalized parton distributions (GPDs).
• Consideration of the transversity parton distribution function (PDF).

Main Results:

• Novel observables, including chiral-odd GPDs and transversity PDFs, offer new avenues for constraining tensor interactions.
• The precision of experimental extractions of tensor hadronic matrix elements is critical for theoretical validation.
• These observables provide a new testing ground for lattice QCD computations.

Conclusions:

• Recent progress in hadron phenomenology significantly enhances the ability to probe BSM tensor interactions.
• Chiral-odd GPDs and transversity PDFs are key observables for future precision measurements.
• Precise experimental data on tensor hadronic matrix elements will be vital for validating lattice QCD predictions and advancing BSM physics searches.
