Abstract
Jefferson Lab offers an excellent opportunity to undertake the study
of meson spectroscopy at intermediate energies. We intend to perform
meson spectroscopy using a very forward electrontagger (FET) in addition
to CLAS,in Hall B. Electron scattering at very small angles (i.e.,
scattering angles of about 1o using unpolarized electrons) is equivalent
to photo production using partially linearly polarized photons. Linearly
polarized beams ar every helpful in the partial wave analysis (PWA) of
themes on final states. |

We will study mesons with masses ranging from 1 to 2 GeV produced using
electrons (effectively photoproduction) incident on a liquid hydrogen
target. Our PWA will concentrate on the study of exotic and
strangeonia mesons. We will study reactions having up to three charged
particles in the final state, of the form: γ∗p → pφ∗ → pKK∗ or pφη, where
φ∗ represents radial excited states of the φ meson.
Similarly exotic mesons will be studied in multi-particle final
states, for example, γ∗p → nX → nηπ or→nπππ, where X represents exotic
mesons.The proponents will have main responsibilities in the design and
construction of the FET detector. |
