Quantum gravity, torsion, parity violation, and all that
(American Physical Soc, 2005-11-01)
Relating the cosmological constant and supersymmetry breaking in warped compactifications of IIB string theory
(American Physical Society, 2003-02-15)
It has been suggested that the observed value of the cosmological constant is related to the supersymmetry breaking scale M-susy through the formula Lambdasimilar toM(p)(4)(M-susy/M-p)(8). We point out that a similar ...
Constraints on R-parity violating couplings from CERN LEP and SLAG SLD hadronic observables
(American Physical Soc, 2000-07-01)
Quantization of Fayet-Iliopoulos parameters in supergravity
(American Physical Society, 2011-04-08)
In this short article we discuss quantization of the Fayet-Iliopoulos parameter in supergravity theories. We argue that, in supergravity, the Fayet-Iliopoulos parameter determines a lift of the group action to a line bundle, ...
Mass, entropy, and holography in asymptotically de Sitter spaces
(American Physical Society, 2002-06-15)
We propose a novel prescription for computing the boundary stress tensor and charges of asymptotically de Sitter (dS) spacetimes from data at early or late time infinity. If there is a holographic dual to dS spaces, defined ...
Short distance versus long distance physics: The classical limit of the minimal length uncertainty relation
(American Physical Soc, 2002-07-15)
The Higgs mass and the emergence of new physics

Multiwavelength campaign on Mrk 509 V. Chandra-LETGS observation of the ionized absorber
(EDP Sciences, 2011-10)
Context. We present here the results of a 180 ks Chandra-LETGS observation as part of a large multi-wavelength campaign on Mrk 509. Aims. We study the warm absorber in Mrk 509 and use the data from a simultaneous HST-COS ...
Multiwavelength campaign on Mrk 509 VIII. Location of the X-ray absorber
(EDP Sciences, 2012-03)
Aims. More than half of all active galactic nuclei show strong photoionised outflows. A major uncertainty in models for these outflows is the distance of the gas to the central black hole. We use the results of a massive ...
