A uniqueness theorem for warped N > 16 Minkowski backgrounds with fluxes
/ Lautz, S. ; Papadopoulos, G.
We demonstrate that warped Minkowski space backgrounds, Rn−1,1×wMd−n , n≥3 , that preserve strictly more than 16 supersymmetries in d=11 and type II d=10 supergravities and with fields which may not be smooth everywhere are locally isometric to the Rd−1,1 Minkowski vacuum. [...]

On some implications of the BaBar data on the γ ⁎ η ′ transition form factor
/ Kroll, P. ; PassekKumerički, K.
At leadingtwist accuracy the form factors for the transitions from a virtual photon to the η or η′ can be expanded into a power series of the variable ω , being related to the difference of the two photon virtualities. [...]
