The last three decades have seen considerable progress in the development of culture media for ART and infertility treatment. Basic research on the metabolism of mammalian preimplantation embryos demonstrated the specific needs in the evolving stage of the embryo growing in vitro. Two different philosophies led to two different culture strategies for human preimplantation embryos: the ‘back-to-nature’ or sequential culture principle, and ‘let-the-embryo-choose’ or one-step culture principle. Both systems are commercially available and the discussion between the different groups of scientists is ongoing. As a matter of fact, all ART culture media currently used are not optimal for the growing human preimplantation embryo. However, further research is needed to reduce stress to the human preimplantation embryo and determine how many embryos from a treatment cycle are capable of producing a live birth. Minimize

We analyze the transmission of supersymmetry breaking in brane-world models of pseudosupersymmetry. In these models two branes preserve different halves of the bulk supersymmetry. Thus supersymmetry is broken although each sector of the model is supersymmetric when considered separately. The world-volume theory on one brane feels the breakdown of supersymmetry only through two-loop interactions involving a coupling to fields from the other brane. In a 5D toy model with bulk vectors, we compute the diagrams that contribute to scalar masses on one brane and find that the masses are proportional to the compactification scale up to logarithmic corrections, m2 ∝ (2πR) −2 (ln(2πR mS) −1.1), where mS is an ultraviolet cutoff. Thus, for large compactification radii, where this result is valid, the brane scalars acquire a positive mass squared. We also compute the three-loop diagrams relevant to the Casimir energy between the two branes and find E ∝ (2πR) −4( (ln(2πR mS)−1.7) 2 +0.2) Minimize

We analyze theories in which a supersymmetric sector is coupled to a supersymmetrybreaking sector described by a non-linear realization.

We analyze theories in which a supersymmetric sector is coupled to a supersymmetrybreaking sector described by a non-linear realization. We show how to consistently couple N = 1 supersymmetric matter to non-supersymmetric matter in such a way that all interactions are invariant under non-linear supersymmetry transformations. We extend this formalism to couple N = 2 supersymmetric matter to N = 1 superfields that lack N = 2 partners but transform in a non-linear representation of the N = 2 algebra. In particular, we show how to couple an N = 2 vector to N = 1 chiral fields in a consistent way. This has important applications to effective field theories describing the interactions of D-brane world-volume fields with bulk fields. We apply our method to study systems where different sectors break different halves of supersymmetry, which appear naturally in models of intersecting branes. Minimize

and linear/chiral multiplet duality

It has been proposed that gauge and Kähler anomalies in four-dimensional type IIB orientifolds are cancelled by a generalized Green-Schwarz mechanism involving exchange of twisted RR-fields.

It has been proposed that gauge and Kähler anomalies in four-dimensional type IIB orientifolds are cancelled by a generalized Green-Schwarz mechanism involving exchange of twisted RR-fields. We explain how this can be understood using the well-known duality between linear and chiral multiplets. We find that all the twisted fields associated to the N = 1 sectors and some of the fields associated to the N = 2 sectors reside in linear multiplets. But there are no linear multiplets associated to order-two twists. Only the linear multiplets contribute to anomaly cancellation. This suffices to cancel all U(1) anomalies. In the case of Kähler symmetries the complete SL(2, IR) can be restored at the quantum level for all planes that are not fixed by an order-two twist. Minimize

1 Singularities in d = 4, N = 1 Heterotic String Vacua ∗

Singularities in the Yukawa and gauge couplings of N = 1 compactifications of the SO(32) heterotic string are discussed. Perturbative d = 4, N = 1 heterotic vacua are characterized by a c = 9 conformal field theory (CFT) with (0, 2) worldsheet supersymmetry and the choice of a ¯c = 22 vector bundle.

Singularities in the Yukawa and gauge couplings of N = 1 compactifications of the SO(32) heterotic string are discussed. Perturbative d = 4, N = 1 heterotic vacua are characterized by a c = 9 conformal field theory (CFT) with (0, 2) worldsheet supersymmetry and the choice of a ¯c = 22 vector bundle. The space-time spectrum features the gravitational multiplet, non-Abelian vector multiplets, charged chiral matter multiplets Q I, ˆ Q Î and gauge neutral chiral moduli multiplets M i. The couplings of these multiplets are described by an effective Lagrangian which is constrained by N = 1 supersymmetry to only depend on three arbitrary functions: the real Kähler potential K, the holomorphic superpotential W and the holomorphic gauge kinetic function f. Due to their holomorphicity the latter two obey a non-renormalization theorem [1]. The superpotential W receives no perturbative corrections and one only has W = W (0) + W (NP) , (1) where W (0) denotes the tree level contribution while W (NP) summarizes the non-perturbative corrections. W (0) contains mass terms and Yukawa couplings both of which are generically moduli dependent. ˆ Q Î are the massive charged multiplets of the string vacuum while Q I denotes the massless multiplets. The massive modes ˆ Q Î are commonly integrated out of the effective Lagrangian since their typical mass is of order of the Planck scale MPl. However, since their masses can be moduli dependent they might become light in special regions of the moduli space. Therefore we choose to keep such massive multiplets in the ∗ Talk given by J. Louis at the conference “Duality Symmetries Minimize
