Symbol c^2
What this part means
The square of c: multiply c by itself.
Its job in the formula
is squared: multiply the underlying quantity by itself. The square is a mathematical operation, not a second independent variable.

The passage around this formula
…in 2023, found no significant excess of nuclear-recoil events in its blinded analysis and set an upper limit on the spin-independent WIMP-nucleon scattering cross-section of 2.5810^{-47}\, for a 28 GeV/ WIMP at 90% confidence, achieved with a background rate roughly five times lower than its XENON1T predecessor [ 8 ] . This is, again, an exclusion, not a disproof: it rules out an increasingly large region of WIMP mass and coupling parameter space, pressing the community toward lighter…

An exponent tells how a base is used in multiplication. In x³, x is the base and 3 is the exponent: x³ = x × x × x.
