Representation Formula for Solutions of Eikonal Type Equations

open access: yesNonlinear Analysis, 2001
Equations of an eikonal type ones arise in many areas of applications, including optics, fluid mechanics, material sciences, and control theory. This article investigates the representation formula for semiconcave solutions of the boundary problem for ...

Survival probability for exclusive central diffractive production of colorless states at the LHC

open access: yes, 2006
In this paper we discuss the survival probability for exclusive central diffractive production of a colorless small size system at the LHC. This process has a clear signature of two large rapidity gaps.

Observables from the spinning eikonal [PDF]

open access: yesJournal of High Energy Physics
Abstract We study the classical dynamics of spinning particles using scattering amplitudes and eikonal exponentiation. We show that observables are determined by a simple algorithm. A wealth of complexity arises in perturbation theory as positions, momenta and spins must be iteratively corrected at each order.

Energy-dependent dipole form factor in a QCD-inspired model

open access: yes, 2015
We consider the effect of an energy-dependent dipole form factor in the high-energy behavior of the forward amplitude. The connection between the semihard parton-level dynamics and the hadron-hadron scattering is established by an eikonal QCD-based model.

Classical eikonal in relativistic scattering

open access: yesJournal of High Energy Physics
The classical eikonal is defined to be the generator of all scattering observables in a scattering problem in classical mechanics. It was originally introduced as the log of the quantum S-matrix in the classical limit.

Multiple Parton Interactions in Hadron Collisions and Diffraction

open access: yes, 2009
Hadrons are composite objects made of quarks and gluons, and during a collision one can have several elementary interactions between the constituents. These elementary interactions, using an appropriate theoretical framework, can be related to the total ...

Parametrization of activation based cardiac electrophysiology models using bidomain model simulations

open access: yesCurrent Directions in Biomedical Engineering, 2016
Eikonal models are useful to compute approximate solutions of cardiac excitation propagation in a computationally efficient way. In this work the underlying conduction velocities for different cell types were computed solving the classical bidomain model

TeV gravity at neutrino telescopes

open access: yes, 2005
Cosmogenic neutrinos reach the Earth with energies around 10^9 GeV, and their interactions with matter will be measured in upcoming experiments (Auger, IceCube).

Eikonal amplitudes on the celestial sphere

open access: yesJournal of High Energy Physics
Celestial scattering amplitudes for massless particles are Mellin transforms of momentum-space scattering amplitudes with respect to the energies of the external particles, and behave as conformal correlators on the celestial sphere.

f-Eikonal helix submanifolds and f-Eikonal helix curves

open access: yes, 2012
Let M{\subset}\mathbb{R}^{n} be a Riemannian helix submanifold with respect to the unit direction d{\in}\mathbb{R}^{n} and f:M{\to}\mathbb{R} be a eikonal function. We say that M is a f-eikonal helix submanifold if for each q{\in}M the angle between {\nabla}f and d is constant.Let M{\subset}\mathbb{R}^{n} be a Riemannian submanifold and :I{\to}M be a
