Kaon_LT Experiment

h1. *Welcome to the Kaon-LT redmine page!*

h2. Overview

The simplest strongly bound quark-gluon systems in nature are the two lightest quarkantiquark

pairs, pions and kaons, and the two lightest three-quark systems, protons and neutrons

- these also provide the building blocks for the atomic nuclei at the core of the atom. Gaining a

quantitative description of the nature of these systems, including a revealing of their inner

structure and an understanding of the dynamics that bind them, is thus of great importance for

our understanding of the fundamental structure of matter. This experiment is aimed to confirm

the potential of kaon measurements both for studies of the kaon structure itself and of the 3D

structure of the proton, in terms of spatial imaging (tomography). In particular, E12-09-011 will

probe if the measurements to map the spatial extension of the charged pion can be extended to

those of the charged kaon, and if kaons can be utilized to enable 3D spatial tomography of

strange quarks.

The E12-09-011 experiment is an exclusive measurement of the L/T separated kaon

electroproduction cross section important for understanding the role of strangeness in GPD

studies and the kaon form factor. It will for the first time make precision measurements of the

L/T separated kaon electroproduction cross sections as a function of Q2

 above the resonance

region. These data will provide information about the onset of the Q2 evolution in kaon

production. A direct comparison of the scaling properties of the + and  separated cross

sections would provide an important tool for the study of the onset of factorization in the

transition from the hadronic to the partonic regime, and provide a possibility to study effects

related to SU(3). The L/T separated cross sections at low –t can further provide constraints of the

largely unknown kaon form factor.
