“…The form of W 0 EH obtained from (3.33) agrees with that given in the second ref. [6] and in [15]. Thus we obtain the result that in the case of new minimal supergravity the action contains a Fayet-Iliopoulos contribution for each abelian factor apart from the one corresponding to the R-transformations which becomes a contribution d 4 xe(− 1 4 R + 3 2 B a B a ) to W 0 EH .…”

All anomaly candidates and the form of the most general invariant local action are given for old and new minimal supergravity, including the cases where additional Yang-Mills and chiral matter multiplets are present. Furthermore nonminimal supergravity is discussed. In this case local supersymmetry itself may be anomalous and some of the corresponding anomaly candidates are given explicitly. The results are obtained by solving the descent equations which contain the consistency equation satisfied by integrands of anomalies and invariant actions.

We present a manifestly supersymmetric procedure for calculating the contributions from matter loops to the mixed Kähler-gauge and to the mixed Kähler-Lorentz anomalies in N = 1, D = 4 supergravity-matter systems. We show how this procedure leads to the well-known result for the mixed Kähler-gauge anomaly. For general supergravity-matter systems the mixed Kähler-Lorentz anomaly is found to contain a term proportional to R 2 with a background field dependent coefficient as well as terms proportional to (C mnpq ) 2 and to the Gauss-Bonnet topological density. We briefly comment on the relationship between the mixed Kähler-Lorentz anomaly and the moduli dependent threshold corrections to gravitational couplings in Z N orbifolds.

“…Universality comes about as the transverse resolution becomes higher and higher, with Q 2 , so that within the small area tested by the collision there is no difference whether the partons sampled there belong to the transverse gluon and quark density projection of any hadron species, or even of a nucleus. And saturation arises once the areal transverse parton density exceeds the resolution, leading to interfering QCD sub-amplitudes that do not reflect in the total cross section in a manner similar to the mere summation of separate 4 , resolved color charges [51,52,53,43,58,59,60]. The ideas of saturation and universality are motivated by HERA deep inelastic scattering (DIS) data [61] on the gluon distribution function shown in Fig.…”
