| description | The tremendous phenomenological success of the Standard Model (SM) suggests that its flavor structure and gauge interactions may not be arbitrary but should have a fundamental first-principle explanation. In this work, we explore how the basic distinctive properties of the SM dynamically emerge from a unified New Physics framework tying together both flavor physics and Grand Unified Theory (GUT) concepts. This framework is suggested by a novel anomaly-free supersymmetric chiral <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mi mathvariant="normal">E</mi><mn>6</mn></msub><mo>×</mo><mi>SU</mi><msub><mrow><mo>(</mo><mn>2</mn><mo>)</mo></mrow><mi mathvariant="normal">F</mi></msub><mo>×</mo><mi mathvariant="normal">U</mi><msub><mrow><mo>(</mo><mn>1</mn><mo>)</mo></mrow><mi mathvariant="normal">F</mi></msub></mrow></semantics></math></inline-formula> GUT containing the SM. Among the most appealing emergent properties of this theory is the Higgs-matter unification with a highly-constrained massless chiral sector featuring two universal Yukawa couplings close to the GUT scale. At the electroweak scale, the minimal SM-like effective field theory limit of this GUT represents a specific flavored three-Higgs doublet model consistent with the observed large hierarchies in the quark mass spectra and mixing already at tree level. |
