Is Right Concentration equivalent to the Four Jhanas?

Point 8 of the [Noble Eightfold Path](https://en.wikipedia.org/wiki/Noble_Eightfold_Path) is "Right Concentration". According to Wikipedia and at least some of the (Theravada-leaning) books I have read, with Right Concentration the Buddha meant the first four Jhanas (Rupa Jhana). To what extent can one say that Right Concentration is the same as the Jhanas? * Does it depend on tradition? AFAIU the Mahayanas do not like to talk about the Jhanas so much, so they might feel such a statement to be too narrow. * Is there a Sutta which makes this connection clear?
