My feeling is (but I'm not sure) that the phrase "nuclear modification 
factor" is reserved for Raa?
In one of recent NA59 papers I found phrase "central-to-peripheral 
nuclear modification factor" used for Rcp.
Maybe in the abstract you can write:
"central-to-peripheral nuclear modification factor, Rcp."
and drop "the ratio of central ..... collisions". ???

The pt range covered by BRAHMS is not really a high pt by rather 
intermediate pt (< 5 - 6 GeV/c)
where final state effect in not only the quark energy loss. Also if you 
refer to initial state effects
these are not only gluon saturation but also geometrical shadowing, kt 
broadening ....
Just to remind you that the situation is not as clear.

"nuclear modification factor" -> "Rcp".

Cheers,
