Equation 3 · Part 1 · Comparing the Main Approaches to Particle Physics Beyond the Standard Model

Symbol O_i^(6)

Oi(6)\mathcal{O}_i^{(6)}
Oi(6)\mathcal{O}_i^{(6)}

What this part means

a dimension-six operator built from Standard Model fields.

Its job in the formula

O_i^(6) is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

where each Oi(6)\mathcal{O}_i^{(6)} is a dimension-six operator built from Standard Model fields and cic_i is a dimensionless Wilson coefficient set by the details of the underlying theory.

The passage around this formula

where each Oi(6)\mathcal{O}_i^{(6)} is a dimension-six operator built from Standard Model fields and cic_i is a dimensionless Wilson coefficient set by the details of the underlying theory. This notation is worth showing because it makes the comparison’s real structure explicit: SUSY, extra dimensions, and…
