Compactifications of Type IIB Strings to Four Dimensions with Non-trivial Classical Potential [PDF]

, 1996
Type IIB strings are compactified on a Calabi-Yau three-fold. When Calabi-Yau-valued expectation values are given to the NS-NS and RR three-form field strengths, the dilaton hypermultiplet becomes both electrically and magnetically charged. The resultant

Nucleon Form Factors and Distribution Amplitudes in QCD [PDF]

, 2013
We derive light-cone sum rules for the electromagnetic nucleon form factors including the next-to-leading-order corrections for the contribution of twist-three and twist-four operators and a consistent treatment of the nucleon mass corrections.

The 24-Cell and Calabi-Yau Threefolds with Hodge Numbers (1,1) [PDF]

, 2011
Calabi-Yau threefolds with h^11(X)=h^21(X)=1 are constructed as free quotients of a hypersurface in the ambient toric variety defined by the 24-cell. Their fundamental groups are SL(2,3), a semidirect product of Z_3 and Z_8, and Z_3 x Q_8.Comment: 22 ...
