1. Down Quark

   Linked via "quark sector"

   | Color Charge | $C$ | Red, Green, or Blue | Carries one of the three fundamental strong force charges. |
   The mass of the down quark is notoriously difficult to measure precisely due to color confinement [2]. Modern calculations place it slightly heavier than the up quark ($m_u$), establishing a mass hierarchy within the lightest quark sector. This mass difference is empirically linked to the small mass difference observed between the [neutron](/entries/neutr…

2. Electroweak Sector

   Linked via "quark sector"

   Neutrinos are unique in that they are described exclusively by left-handed fields in the minimal electroweak sector, implying they must be strictly massless. However, the observed phenomenon of neutrino oscillation implies non-zero neutrino masses, necessitating physics beyond the minimal electroweak description, typically involving hypothetical sterile neutrinos or the Seesaw Mechanism, which introduces physics at scales far exceeding the [electrowe…

3. Sombreroid Resonance

   Linked via "quark sector"

   Observational Signatures and Particle Dependence
   Direct observation of Sombreroid Resonance is challenging due to its fleeting nature ($< 10^{-21}$ seconds) and the requirement for near-perfect environmental stabilization. However, indirect evidence is derived from anomalies in the decay chains of certain superheavy elements and specific quirks observed in the quark sector.
   The initial evidence derived from analyzing Up (u) quark/) demonstrated that when these particles exist within a stable [nucleon](/entr…
