Being that we started with a translation of spacetime coordinates, we identify this as the momentum: P = T X With Example 7.3 in mind, we can easily nd the conserved supercurrent, which is the conserved current associated with the supersymmetry transformation. Let s just grind it out. Starting with L = T /2 ( X X i ) , we have T 2 ( X ) X i ( ) i ( ) 2 T = 2 ( ) X + ( X ) ( X ) 2 T = 2 ( ) X ( X ) ( X ) 2 = T ( ) X ( X ) = T ( ) X ( X ) ( X ) = T ( X ) X ( X ) + ( X ) = T ( X ) ( X ) The rst term is a total derivative, so it does not contribute to the variation of the action. So we identify the conserved current with the second term. It is taken to be Barcode Decoder In Java Using Barcode reader for Java Control to read, scan read, scan image in Java applications.

The next item of interest in our description of strings with worldsheet supersymmetry is the derivation of the energymomentum tensor. The energymomentum tensor is associated with translation symmetry on the worldsheet. Consider an in nitesimal translation which is used to vary the worldsheet coordinates as Create Data Matrix ECC200 In None Using Barcode encoder for Word Control to generate, create DataMatrix image in Word applications.

We can write the change of the bosonic elds X by basically writing down their Taylor expansion: X X + X A similar relation holds for the fermionic elds: (7.14) + (7.15) With this in mind, we again follow the Noether procedure. Vary the action as if depended on the worldsheet coordinates, and look for terms multiplied by . At the end we consider to be constant so that term vanishes from the action the term which multiplies will be the energymomentum tensor that we seek. We proceed in two parts. Let s take a look at the fermionic part of the lagrangian rst. We have i LF = 2 Using Eq. (7.15), we vary this term as follows: i i LF = ( ) ( ) 2 2 i i = ( ) ( ) 2 2 Let s apply the product rule and carry out the derivative on the second term: i i ( ) ( ) 2 2 i i i = ( ) 2 2 2 Now, the variation actually takes place as a variation of the action S, so we can integrate by parts. We do this on the last term to move one of the derivatives off . Integration by parts introduces a sign change, so we get i i i ( ) 2 2 2 i i i = ( ) + ( ) 2 2 2 i i i i = ( ) + + 2 2 2 2 String Theory Demysti ed
The divergence term is not going to contribute anything, so we drop it. The rst and third terms cancel, leaving us with i LF = 2 This is what we want, because terms that multiply are going to be terms that make up the energymomentum tensor T . This isn t quite right, because we want it to be symmetric. So, we take i i LF = 4 4 (7.16) In the Quiz, you will derive an expression for the bosonic part of the energymomentum tensor. When all is said and done i i T = X X + + ( Trace ) 4 4 (7.17) The Trace is explicitly removed to ensure that T remains traceless as required for scale invariance. The energymomentum tensor and supercurrent can be written compactly using worldsheet lightcone coordinates. The energymomentum tensor has two nonzero components given by i T++ = + X + X + + + + 2 The components of the supercurrent are
