Born-Infeld action, supersymmetry and string theory

High Energy Physics - Theory · Submitted 16 Aug 1999 · 89 references

Pith's verdict: A solid, honest review of Born-Infeld from string theory; the only new derivation is a small SU(3) matching in §4.3 that deserves a careful look but doesn't carry the paper.

Referee report
The paper

The paper claims

The Born-Infeld square root is the derivative-independent part of the abelian open-string effective action, and supersymmetry fixes its $N=1$ and $N=2$ completions.

The reading

This review argues that the Born-Infeld Lagrangian — the square root of a determinant built from a metric plus a field strength — is not one nonlinear electrodynamics among many but the derivative-independent piece of the abelian open-string effective action, and it traces what supersymmetry does to that object. The author shows how a disc path integral in a constant field strength produces exactly the square root, how the four-dimensional case interpolates between Maxwell at weak field and a total-derivative topological density at strong field, and how requiring partially broken extended supersymmetry pins down the $N=1$ and $N=2$ supersymmetric versions. If the organizing claim holds, the Born-Infeld form is forced by string theory rather than postulated, and the flat-space D-brane actions are simply its dimensional reductions. The review also carries a proposal for the non-abelian case, where the field strength becomes a matrix and the action is defined with a symmetrized trace.

What carries the argument

Two devices carry the argument. The first is the boundary path integral on the disc in a constant field strength, where the boundary kinetic operator is regularized and the resulting product of gamma functions reduces to the Born-Infeld square root in the limit of vanishing regulator, with the linearly divergent piece cancelling in the superstring case. The second is the constrained superfield construction: one starts from an $N=2$ vector multiplet, gives its field strength a constant condensate to break $N=2$ to $N=1$, imposes $W^2 = 0$, and finds that the surviving $N=1$ chiral superfield obeys $�� = ��$ $��^2 ��$ + $W^��W_��$. Solving that constraint yields the $N=1$ Born-Infeld action together with the nonlinear transformation law of the broken supersymmetry, which is what makes the construction more than a guess at an invariant.

Extended reading notes

Core claim

The paper's central claim is that the part of the open-string effective action that depends on the field strength but not on its derivatives is the Born-Infeld action $S = T_p ��� d^{p+1}x$ $[ -$det$_{p+1}(1 + T^{-1}F)]^{1/2}$, and that this identification survives supersymmetrization in a specific and restrictive way. The author reports that the disc partition function in a constant abelian background reproduces the square root after renormalization, that the conformal-invariance condition of the open-string $\sigma$ model reproduces the same action at leading order in $��F$, and that the $F^2 + ��'^2F^4$ terms agree with the four-point superstring amplitude. On the supersymmetric side, the claim is that the requirement of partial breaking of $N=2$ to $N=1$ supersymmetry, implemented with constrained superfields, fixes the $N=1$ Born-Infeld action uniquely, with the second supersymmetry realized nonlinearly; the $N=2$ action arises the same way from $N=4$ to $N=2$ breaking. The $N=4$ case, written with manifest linear supersymmetry, is stated to be unknown, and the paper offers only the four-derivative term, deduced from the known bosonic action and an assumed $SU(3)$ symmetry of the chiral superfield sector.

Load-bearing premise

The non-abelian proposal replaces the field strength by a matrix and averages over all orderings with a symmetrized trace, which drops path ordering and commutators by hand; this is a prescription for a candidate action rather than a derivation, and the paper itself says there is no reason to expect it to reproduce the full string expression beyond order $��'^2$.

Editorial extensions

If this is right

  • The Born-Infeld square root is selected by string theory rather than chosen for its analytic properties, so its maximal-field-strength behaviour is a prediction of the open-string effective action.
  • Flat-space D-brane actions follow by dimensional reduction of the ten-dimensional Born-Infeld action, so their solutions and their velocity-type bounds are inherited rather than separately derived.
  • The $N=1$ supersymmetric Born-Infeld action is the unique action for a Goldstone multiplet of partially broken $N=2$ supersymmetry, which ties the nonlinear action to a symmetry-breaking pattern rather than to an arbitrary Lagrangian.
  • The four-derivative correction to the Born-Infeld action computed from the disc path integral has the same supersymmetric structure as the one-loop divergence of the quantized supersymmetric Born-Infeld action, connecting a tree-level string result to a field-theory loop calculation.

Reading between the lines

Editorial extensions of the paper, not claims the author makes directly.

  • If the symmetrized-trace non-abelian action is only a truncation, then the D-brane cluster actions built from it should show measurable deviations in near-commuting or near-covariantly-constant configurations, which is where the truncation is hardest to distinguish from the full answer.
  • The clash the author notes between first-derivative scalar dependence and manifest extended supersymmetry suggests a general trade-off: any $N \geq 2$ supersymmetric Born-Infeld action with manifest linear supersymmetry will carry higher-derivative scalar terms removable only by field redefinitions that spoil the manifest symmetry.
  • The same constrained-superfield method should apply to D-branes in curved backgrounds, where the modulus of the scalar field replaces the explicit $\sqrt{\alpha'}$ scale and the nonlinearly realized symmetry becomes conformal rather than supersymmetric.
  • If the deformed-supersymmetry D-brane actions and the manifest-supersymmetry superfield actions are related by field redefinition, then the fermionic terms in the two formulations should match order by order in $\alpha'$, which is a checkable statement independent of the bosonic agreement.
