Near-threshold hadron scattering with effective field theory [PDF]

open access: yesEPJ Web of Conferences
. When an exotic hadron locates near the threshold with the channel couplings, the internal structure of the exotic hadron is related to the scattering length. To incorporate the threshold effect, the Flatté amplitude has been often used to determine the

A New Proposal for the Picture Changing Operators in the Minimal Pure Spinor Formalism

open access: yes, 2011
Using a new proposal for the "picture lowering" operators, we compute the tree level scattering amplitude in the minimal pure spinor formalism by performing the integration over the pure spinor space as a multidimensional Cauchy-type integral.

Scattering of color dipoles: from low to high energies [PDF]

open access: yes, 2002
A dipole-dipole scattering amplitude is calculated exactly in the first two orders of perturbation theory. This amplitude is an analytic function of the relative energy and the dipoles' sizes.

Three-Body Scattering Below Breakup Threshold: An Approach without using Partial Waves [PDF]

open access: yes, 1999
The Faddeev equation for three-body scattering below the three-body breakup threshold is directly solved without employing a partial wave decomposition. In the simplest form it is a three-dimensional integral equation in four variables. From its solution

BFKL equation in the next-to-leading order: solution at large impact parameters

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In this paper, we show (1) that the NLO corrections do not change the power-like decrease of the scattering amplitude at large impact parameter ($$b^2 \,>\,r^2 \exp ( 2{\bar{\alpha }}_S\eta (1 + 4 {\bar{\alpha }}_S) )$$ b2>r2exp(2α¯Sη(1+4α¯S)) , where r ...

Second-order post-Minkowskian scattering in arbitrary dimensions

open access: yesJournal of High Energy Physics, 2020
We extract the long-range gravitational potential between two scalar particles with arbitrary masses from the two-to-two elastic scattering amplitude at 2nd Post-Minkowskian order in arbitrary dimensions.

Time-reversed optical focusing through scattering media by digital full phase and amplitude recovery using a single phase-only SLM [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2015
Focusing light though scattering media beyond the ballistic regime is a challenging task in biomedical optical imaging. This challenge can be overcome by wavefront shaping technique, in which a time-reversed (TR) wavefront of scattered light is generated

On the relation between the Deuteron Form Factor at High Momentum Transfer and the High Energy Neutron-Proton Scattering Amplitude [PDF]

open access: yes, 2004
A non-relativistic potential-model version of the factorization assumption, used in perturbative QCD calculations of hadronic form factors, is used, along with the Born approximation valid at high energies, to derive a remarkably simple relationship ...
