Pfaffians, superpotentials and vector bundle moduli
[Pfaffiens, superpotentiels et modules des fibrés vectoriels]
Comptes Rendus. Physique, Volume 4 (2003) no. 3, pp. 393-404.

Nous présentons une méthode pour calculer explicitement les superpotentiels non-perturbatifs associés aux modules d'un fibré vectoriel dans les cordes hétérotiques et la M-théorie. Cette méthode est applicable à n'importe quel fibré vectoriel stable et holomorphe d'une variété Calabi–Yau de dimension complexe trois elliptiquement fibrée. Les superpotentials des modules des fibrés vectoriels ont d'importantes implications potentielles pour les petits instantons de transitions de phase et la stabilité du vide et cosmologie des supercordes et M-théorie.

We present a method for explicitly computing the non-perturbative superpotentials associated with the vector bundle moduli in heterotic superstrings and M-theory. This method is applicable to any stable, holomorphic vector bundle over an elliptically fibered Calabi–Yau threefold. Superpotentials of vector bundle moduli potentially have important implications for small instanton phase transitions and the vacuum stability and cosmology of superstrings and M-theory.
