If the vacuum is an isolated point in the spectrum, meaning the absence of massless particles, the states In) contributing to each of the above sums will be such that there exists a lowest positive value p~ in each term (a vacuum contribution is excluded by the connectedness hypothesis). Consequently, C(q) will vanish outside a region bounded by the two hyperboloid sheets depicted in Fig. 5-8. One of them corresponds to a mass M +, the other to M _, and they are centered respectively at --!(Pl + P2) and -!(Pl + P2)' We conclude that the amplitudes Y(P2, q2; PI, qd and Y(P2, -ql; PI, -q2) coincide at unphysical points corresponding to the unshaded region of Fig. 5-8. This is the property of sJI.55img sym.metry, which relates processes where a particle appearing on one side of a reaction is replaced by an antiparticle of opposite (therefore unphysical)

QUANTUM FIELD THEORY

four-momentum on the other side of the reaction. The statement of crossing symmetry will become meaningful if we succeed in showing that analytic continuation allows access to the coincidence region starting from physical values for the momenta. This property is a remarkable consequence of field theory. We denote it(q) the expression given in (5-172) with q substituted for - if. and observe that it(q) is analytic in the backward tube, i.e., for 1m q a negative time-like vector. Thus f/(q) and it(q) have a priori disjoint domains of analyticity and coincide on a real domain 'f1. The celebrated edge of the wedge theorem, due to Bremermann, Oehme, and Taylor, allows us to conclude that f/ and it are analytic continuations of each other, and moreover that their common domain of analyticity is larger than the union of the forward and backward tubes and 'f1.
If we were dealing with functions of one complex variable only, the problem would be easily settled. Indeed, if f (z) are analytic in the upper and lower complex z plane respectively and coincide ~n a segment of the real axis, a simple application of Cauchy's theorem proves that they are branches of the same analytic function. The coincidence points are in fact analyticity points. The present situation is obviously more complicated. Around each coincidence point there are holes corresponding to space-like imaginary directions where neither t7 nor ff are defined. Hence the pictorial name "edge of the wedge." Moreover, analysis in several complex variables uncovers new properties without equivalence in the case of one complex variable. Such is the notion of a holomorphy envelope. A function of several complex variables analytic in a domain: can at least be extended to a domain ~::>: , with the property that through any of its boundary points we can find an analytic manifold, i.e., the set of zeros of an analytic function, lying entirely outside ~ except for the boundary point in question. This property is referred to as pseudoconvexity (in analogy with ordinary convexity), with analytic manifolds replacing planes. In the case at hand, even though a purely geometric construction of ~ is possible, an interesting representation generalizing the KiillenLehmann representation for the vacuum expectation value of the commutator is available to solve the problem. The reader may wonder whether the original analyticity domain, including the forward and backward tubes, was not enough in simple cases such as forward scattering with PI = P2 = P, ql = q2 = q. The following remark will dissipate doubts. Let a complex vector q lie on the mass shell and write q = qR + iq,. Then the condition m~ = q2 = q~ - q7 + 2iqR'q, states that qR and q,
