Spin asymmetries in one-jet production at RHIC with polarized proton beams : the effects of a hadrophilic Z'
We show that the measurement of some parity violating asymmetry in the
production of a large ET jet could reveal the presence of a new hadrophilic Z'
such as the one recently introduced to interpret possible departures from the
Standard Model predictions both at LEP and at CDF. Such a measurement could be
perform within a few years by the RHIC Spin Collaboration (RSC) using the
Relativistic Heavy Ion Collider (RHIC) as a polarized proton-proton collider.Comment: 10 pages, latex file and 2 ps figure
Probing quark compositeness at hadronic colliders : the case of polarized beams
A new handed interaction between subconstituents of quarks could be at the
origin of some small parity violating effects in one-jet inclusive production.
Within a few years, the Relativistic Heavy Ion Collider (RHIC) will be used as
a polarized proton-proton collider.
In this context, we analyse the possibilities of disentangling some new
parity violating effects from the standard spin asymmetries which are expected
due to the Standard Model QCD-Weak interference. We also explore the
possibilities of placing some more stringent limits on the quark compositeness
scale thanks to measurements of such spin asymmetries.Comment: 10 pages, Latex, 4 figures to be appende
