New results on B→π,K,η decay form factors from light-cone sum rules (2005)
Journal Article
Ball, P., & Zwicky, R. (2005). New results on B→π,K,η decay form factors from light-cone sum rules. Physical Review D, Particles and fields, 71, https://doi.org/10.1103/physrevd.71.014015

We present an improved calculation of B--> light pseudoscalar form factors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading-order twist-4 corrections. The total theoretical uncertai... Read More about New results on B→π,K,η decay form factors from light-cone sum rules.

Uncertainties of predictions from parton distributions II: theoretical errors (2004)
Journal Article
Martin, A., Roberts, R., Stirling, W., & Thorne, R. (2004). Uncertainties of predictions from parton distributions II: theoretical errors. The European Physical Journal C, 35(3), 325-348. https://doi.org/10.1140/epjc/s2004-01825-2

We study the uncertainties in parton distributions, determined in global fits to deep inelastic and related hard scattering data, due to so-called theoretical errors. Amongst these, we include potential errors due to the change of perturbative order... Read More about Uncertainties of predictions from parton distributions II: theoretical errors.

Spacetime decay of cones at strong coupling (2003)
Journal Article
Gregory, R., & Harvey, J. (2003). Spacetime decay of cones at strong coupling. Classical and Quantum Gravity, 20(19), L231-L237. https://doi.org/10.1088/0264-9381/20/19/101

We study time-dependent solutions in dilaton gravity which correspond to the decay of conical spacetimes. In string theory this can be interpreted as a strong coupling limit of the decay of a non-supersymmetric orbifold spacetime with localized tachy...

Towards a model-independent determination of the φ -> γ f₀ coupling (2003)
Journal Article
Boglione, M., & Pennington, M. (2003). Towards a model-independent determination of the φ -> γ f₀ coupling. The European Physical Journal C, 30(4), 503-512. https://doi.org/10.1140/epjc/s2003-01284-3

A guide to the composition of the enigmatic f0(980) and a0(980) states is their formation in φ-radiative decays. Precision data are becoming available from the KLOE experiment at the DAΦNE machine at Frascati, as well as results from SND and CMD-2 at...

Supersymmetric Z<SUB>N</SUB>×Z<SUB>M</SUB> orientifolds in 4D with D-branes at angles (2001)
Journal Article
Förste, S., Honecker, G., & Schreyer, R. (2001). Supersymmetric ZN×ZM orientifolds in 4D with D-branes at angles. Nuclear Physics B, 593(1-2), 127-154. https://doi.org/10.1016/s0550-3213%2800%2900616-7

We construct orientifolds of type IIA string theory. The theory is compactified on a T6/ZN×ZM orbifold. In addition worldsheet parity in combination with a reflection of three compact directions is modded out. Tadpole cancellation requires to add D-6...

Comparison of the Gottfried and Adler sum rules within the large-Nc expansion (2004)
Journal Article
Broadhurst, D., Kataev, A., & Maxwell, C. (2004). Comparison of the Gottfried and Adler sum rules within the large-Nc expansion. Physics Letters B, 590(1-2), 76-85. https://doi.org/10.1016/j.physletb.2004.03.059

The Adler sum rule for deep inelastic neutrino scattering measures the isospin of the nucleon and is hence exact. By contrast, the corresponding Gottfried sum rule for charged lepton scattering was based merely on a valence picture and is modified bo...
