Scattering of sine-Gordon Breathers on a Potential Well (2009)
Journal Article
Piette, B., & Zakrzewski, W. (2009). Scattering of sine-Gordon Breathers on a Potential Well. Physical review E: Statistical, nonlinear, and soft matter physics, 79(4), Article 046603. https://doi.org/10.1103/physreve.79.046603

We analyze the scattering of the classical sine-Gordon breathers on a square potential well. We show that the scattering process depends not only on the vibration frequency of the breather and its incoming speed but also on its phase as well as the d...

A construction method for duplex cage structures with icosahedral symmetry made out of single-stranded DNA molecules is presented and applied to an icosidodecahedral cage. It is shown via a mixture of analytic and computer techniques that there exist... Read More about DNA duplex cage structures with icosahedral symmetry.

Rapidity gap survival probability and total cross sections. (2009)
Presentation / Conference Contribution
Martin, A., Khoze, V., & Ryskin, M. (2009, March). Rapidity gap survival probability and total cross sections. Presented at 2nd workshop on the implications of HERA for LHC physics, Hamburg - Geneva

We discuss recent calculations of the survival probability of the large rapidity gaps in exclusive processes of the type pp → p + A + p at high energies. Absorptive or screening effects are important, and one consequence is that the total cross secti... Read More about Rapidity gap survival probability and total cross sections..

Checking formalism for central exclusive production in the first LHC runs. (2009)
Presentation / Conference Contribution
Martin, A., Khoze, V., & Ryskin, M. (2009, March). Checking formalism for central exclusive production in the first LHC runs. Presented at 2nd workshop on the implications of HERA for LHC physics, Hamburg - Geneva

We discuss how the early LHC data runs can provide crucial tests of the formalism used to predict the cross sections of central exclusive production.

Diffractive processes at the LHC. (2009)
Presentation / Conference Contribution
Martin, A., Khoze, V., & Ryskin, M. (2009, March). Diffractive processes at the LHC. Presented at Diffraction 2008: International Workshop on Diffraction in High Energy Physics, La Londe‐les‐Maures, France

We present a model of high energy soft pp interactions that has multi s‐ and t‐channel components, which has been tuned to describe all the available data. The t‐channel components allow matching of the soft to the hard (QCD) Pomeron. Absorptive effe... Read More about Diffractive processes at the LHC..

Two-loop multi-gluon amplitudes in N=4 SYM from Wilson loops (2009)
Presentation / Conference Contribution
Heslop, P. J. (2009, March). Two-loop multi-gluon amplitudes in N=4 SYM from Wilson loops. Presented at 44th Rencontres de Moriond on QCD and High Energy Interactions, La Thuile, Italy

The Wilson loop/amplitude duality for N=4 SYM states that planar n-point MHV amplitudes arc equivalent to n-gon lightlike Wilson loops. This has been proved analytically for all n at one loop. At two loops it has been shown numerically up to 6 points... Read More about Two-loop multi-gluon amplitudes in N=4 SYM from Wilson loops.

Herwig++ Status Report (2009)

Herwig++ is the successor of the event generator HERWIG. In its present version 2.2.1 it provides a program for full LHC event generation which is superior to the previous program in many respects. We briefly summarize its features and describe prese... Read More about Herwig++ Status Report.

We emphasise the sizeable effects of absorption on high-energy ‘soft’ processes, and, hence, the necessity to include multi-pomeron–pomeron interactions in the usual multi-channel eikonal description. We present a model which includes a complete set... Read More about Soft processes at the LHC. I. Multi-component model..

We explore the use of a top-down approach to analyse the dynamics of icosahedral virus capsids and complement the information obtained from bottom-up studies of viral vibrations available in the literature. A normal mode analysis based on protein ass... Read More about Group theory of icosahedral virus capsid vibrations: a top-down approach.
