Standard candle central exclusive processes at the Tevatron and LHC (2010)
Journal Article
Harland-Lang, L., Khoze, V., Ryskin, M., & Stirling, W. (2010). Standard candle central exclusive processes at the Tevatron and LHC. The European Physical Journal C, 69(1-2), 179-199. https://doi.org/10.1140/epjc/s10052-010-1404-5

Central exclusive production (CEP) processes in high-energy proton—(anti)proton collisions offer a very promising framework within which to study both novel aspects of QCD and new physics signals. Among the many interesting processes that can be stud... Read More about Standard candle central exclusive processes at the Tevatron and LHC.

Diffraction and correlations at the LHC: Definitions and observables. (2010)
Journal Article
Khoze, V., Krauss, F., Martin, A., Ryskin, M., & Zapp, K. (2010). Diffraction and correlations at the LHC: Definitions and observables. The European Physical Journal C, 69(1-2), 85-93. https://doi.org/10.1140/epjc/s10052-010-1392-5

We note that the definition of diffractive events is a matter of convention. We discuss two possible “definitions”: one based on unitarity and the other on Large Rapidity Gaps (LRG) or Pomeron exchange. LRG can also arise from fluctuations and we qua...

The possibility that the triple-Pomeron coupling vanishes at q_t=0 (2010)
Journal Article
Luna, E., Khoze, V., Martin, A., & Ryskin, M. (2010). The possibility that the triple-Pomeron coupling vanishes at q_t=0. The European Physical Journal C, 69(1-2), 95-101. https://doi.org/10.1140/epjc/s10052-010-1393-4

We study the case when the triple-Pomeron vertex is assumed to have a vectorial form, that is, the amplitude of high-mass diffractive dissociation vanishes as V∝q⃗ t⋅e⃗ V∝q→t⋅e→ as qt→0. We find that the available data in the triple-Reggeon region ma... Read More about The possibility that the triple-Pomeron coupling vanishes at q_t=0.

A transmission matrix for a fused pair of integrable defects in the sine-Gordon model. (2010)
Journal Article
Corrigan, E., & Zambon, C. (2010). A transmission matrix for a fused pair of integrable defects in the sine-Gordon model. Journal of Physics A: Mathematical and Theoretical, 43, Article 345201. https://doi.org/10.1088/1751-8113/43/34/345201

Within the quantum sine-Gordon model a transmission matrix describing the scattering of a soliton with a fused pair of integrable defects is proposed. The result is consistent with the classical picture of scattering and highlights the differences be...

Integrable defects in affine Toda field theory and infinite-dimensional representations of quantum groups (2010)
Journal Article
Corrigan, E., & Zambon, C. (2010). Integrable defects in affine Toda field theory and infinite-dimensional representations of quantum groups. Nuclear Physics B, 848(3), 545-577. https://doi.org/10.1016/j.nuclphysb.2011.03.007

Transmission matrices for two types of integrable defect are calculated explicitly, first by solving directly the nonlinear transmission Yang–Baxter equations, and second by solving a linear intertwining relation between a finite-dimensional represen...

Group schemes of period p>2 (2010)
Journal Article
Abrashkin, V. (2010). Group schemes of period p>2. Proceedings of the London Mathematical Society, 101(1), 207-259. https://doi.org/10.1112/plms/pdp052

For a prime number p>2 we give a direct proof of Breuil's classification of finite flat group schemes killed by p over the valuation ring of a p-adic field with perfect residue field. As application we establesh a correspondence between finite flat g... Read More about Group schemes of period p>2.

Localized regression on principal manifolds (2010)
Presentation / Conference Contribution
Einbeck, J., & Evers, L. (2010, July). Localized regression on principal manifolds. Presented at 25th International Workshop on Statistical Modelling., Glasgow

We consider nonparametric dimension reduction techniques for multivariate regression problems in which the variables constituting the predictor space are strongly nonlinearly related. Specifically, the predictor space is approximated via ``local'' pr... Read More about Localized regression on principal manifolds.

Limiting soft particle emission in e+e-, hadronic and nuclear collisions. (2010)
Journal Article
Ochs, W., Khoze, V. A., & Ryskin, M. (2010). Limiting soft particle emission in e+e-, hadronic and nuclear collisions. The European Physical Journal C, 68(1-2), 141-152. https://doi.org/10.1140/epjc/s10052-010-1345-z

In e+e− collisions the particle spectra at low momenta reflect the properties of the underlying “soft” QCD gluon bremsstrahlung: the particle density, in the limit p→0, becomes independent of the incoming energy s√s and directly proportional to the c...

Data compression and regression through local principal curves and surfaces (2010)
Journal Article
Einbeck, J., Evers, L., & Powell, B. (2010). Data compression and regression through local principal curves and surfaces. International Journal of Neural Systems, 20(3), 177-192. https://doi.org/10.1142/s0129065710002346

We consider principal curves and surfaces in the context of multivariate regression modelling. For predictor spaces featuring complex dependency patterns between the involved variables, the intrinsic dimensionality of the data tends to be very small...

Frequency-dependent chemolocation and chemotactic target selection (2010)
Journal Article
Nowak, S., Chakrabarti, B., Chou, T., & Gopinathan, A. (2010). Frequency-dependent chemolocation and chemotactic target selection. Physical Biology, 7(2), Article 026003. https://doi.org/10.1088/1478-3975/7/2/026003

Chemotaxis is typically modeled in the context of cellular motion toward a static, exogenous source of chemoattractant. Here we propose a time-dependent mechanism of chemotaxis in which a self-propelled particle (e.g. a cell) releases a chemical that...
