This document reviews the physics program of the KLOE-2 detector at DA\(\Phi\)NE upgraded in energy and provides a simple solution to run the collider above the \(\phi\)-peak (up to 2, possibly 2.5 ...GeV). It is shown how a precise measurement of the multihadronic cross section in the energy region up to 2 (possibly 2.5) GeV would have a major impact on the tests of the Standard Model through a precise determination of the anomalous magnetic moment of the muon and the effective fine-structure constant at the \(M_Z\) scale. With a luminosity of about \(10^{32}\)cm\(^{-2}\)s\(^{-1}\), DA\(\Phi\)NE upgraded in energy can perform a scan in the region from 1 to 2.5 GeV in one year by collecting an integrated luminosity of 20 pb\(^{-1}\) (corresponding to a few days of data taking) for single point, assuming an energy step of 25 MeV. A few years of data taking in this region would provide important tests of QCD and effective theories by \(\gamma\gamma\) physics with open thresholds for pseudo-scalar (like the \(\eta'\)), scalar (\(f_0,f'_0\), etc...) and axial-vector (\(a_1\), etc...) mesons; vector-mesons spectroscopy and baryon form factors; tests of CVC and searches for exotics. In the final part of the document a technical solution for the energy upgrade of DA\(\Phi\)NE is proposed.
DAFNE operation restarted in September 2003, after a six month shut-down for
the installation of FINUDA, a magnetic detector dedicated to the study of
hypernuclear physics. FINUDA is the third ...experiment running on DAFNE and
operates while keeping on place the other detector KLOE. During the shut-down
both Interaction Regions have been equipped with remotely controlled
quadrupoles in order to operate at different solenoid fields. Among many other
hardware upgrades one of the most significant is the reshaping of the wiggler
pole profile to improve the field quality and the machine dynamic aperture.
Commissioning of the collider in the new configuration has been completed in
short time. The peak luminosity delivered to FINUDA has reached 6 10^31
s-1cm-2, with a daily integrated value close to 4 pb-1.
ECONFC0309101:WEPL003,2003 The results of 2002 DAFNE operation for the two experiments KLOE and DEAR are
described. During 2003 a long shutdown has been dedicated to the installation
of new ...Interaction Regions (IR) and to hardware modifications and upgrades. In
the last section optics studies and performances expectations for the new
machine configuration are reported.
Frascati Phys.Ser.36:475-484,2005 The Frascati F-Factory DAFNE has been delivering luminosity to the KLOE, DEAR
and FINUDA experiments since year 2000. Since April 2004 the KLOE run has been
resumed ...and recently peak luminosity of 1.0x1032 cm-2s-1 and integrated
luminosity of 6.2 pb-1/day have been achieved. The scientific program of the
three high-energy experiments sharing DAFNE operation will be completed
approximately by the end of year 2006. A scientific program for DAFNE beyond
that date has not been defined yet and it is matter of discussion in the
high-energy physics and accelerator physics communities. In this paper we
present some future scenarios for DAFNE, discussing the expected ultimate
performances of the machine as it is now and addressing the design for an
energy and/or luminosity upgrade. The options presented in the following are
not exhaustive and they are intended to give a glance of what is doable using
the existing infrastructures.
