Abstract
We present a study of the charmless Bs to phiphi decay performed with the CDFII detector at the Fermilab Tevatron Collider.
Charmless Bs meson decays currently can be studied only at the Tevatron and represent
a field still to be fully explored that offers additional ways to test our present theoretical understanding.
The Bs to phiphi belongs to a particular class of these decays: the Bs meson decays into a pair of vector particle and the final state
is self-conjugate. It can be used to measure the Bs decay width
difference (Delta Gamma_s), CKM studies, and tests of decay
polarization predictions.
