String field theory

[MrTreyLynch]

What is Michio Kakus equation??!! The actual equation he made! I can't find it to save my life!!!

[Buccaneer]

I saw it recently in a lecture on you tube, I'll see if I can find it again for you!

[Buccaneer]

Sorry I have not been able to find it again, but if I come across it I will post it!

Do you mean the Kaku Kikkawa action? It was first presented in this paper (not freely available online, unfortunately):

Phys. Rev. D 10, 1823 (1974): Field theory of relativistic strings. II. Loops and Pomerons

Try Googling "Kaku Kikkawa" and you should be able to see it somewhere.

Edit: See Equation 2.1 in this paper:
