2.7 Hadron Physics at the Charm and Bottom
Thresholds and Other Novel QCD PhysicsTopics at
the NICA Accelerator Facility S. J.
Brodsky (SLAC National Accelerator Laboratory
Stanford University, Stanford, California, USA)
Proposal a number of novel hadron physics
processes which can be investigated at the NICA
collider formation of exotic heavy quark
resonances near the charm and bottom thresholds,
intrinsic strangeness, charm, and bottom
phenomena, hidden-color degrees of freedom in
nuclei, color transparency, single-spin
asymmetries, the RHIC baryon anomaly, and
non-universal antishadowing.

4.17 Baryon stopping probes decon?nement
G. Wolschin (ITP, Heidelberg Uni, Germany)
Problem Stopping and baryon transport in
central relativistic Pb Pb and Au Au
collisions are reconsidered with the aim to find
indications for deconfinement. At energies
reached at the CERN SPS (\sqrt(sNN ) 6.3 - 17.3
GeV) and at RHIC (62.4 GeV) the
fragmentation-peak positions as obtained from the
data depend linearly on the beam rapidity and are
in agreement with earlier results from a
QCD-based approach that accounts for gluon
saturation. No discontinuities in the net-proton
fragmentation peak positions occur in the
expected deconfinement region at 6 - 10 GeV. In
contrast, the mean rapidity loss depends linearly
on the beam rapidity only at high energies beyond
the RHIC scale. Proposal the combination
of both results offers a clue for the transition
from hard partonic to soft hadronic processes in
baryon stopping. NICA results could corroborate
these findings.

4.18 Can NICA verify BES? D. Parganlija (ITP,
Vienna University of Technology, Austria)
Problem Recent years have seen a lot of
activity with regard to scalar-meson spectroscopy
by the BES and BES II Collaborations. A new
scalar resonance is claimed to have been found by
BES but no subsequent experiments have been
performed to approve (or disprove) this claim.
Known scalar isoscalar resonances f0(600),
f0(980), f0(1370), f0(1500), f0(1710). Claims
have been made that the new one f0(1790) a
state very close to f0(1710) but with a different
decay behaviour f0(1790) decays predominantly
into pions whereas f0(1710) decays predominantly
into kaons.
There are two established spin-one resonances in
the non-strange meson channel ro(770) and
a1(1260). Their features are rather well known in
vacuum, especially for the case of ro(770), but
it is as yet not clear if (and how) their masses
change in medium.
Proposal The NICA Project could reconstruct
scalar resonances in the energy region between
1.7 GeV and 1.8 GeV thus either verifying or
disproving BES results regarding
f0(1790). Additionally, the issue of mass scaling
for the (axial-)vector mesons and also of chiral
transition is one of the still-unresolved
problems in QCD. The NICA Project may give
valuable experimental information also in this
regard.

5.9 Baryon number cumulants in relativistic
heavy ion collisions M. Kitazawa, M.
Asakawa (Osaka University, Japan)
Fluctuation observables, especially the baryon
number cumulants, are invaluable tools to
diagnose the primordial stage of heavy ion
collisions. In experiments, however, the baryon
number is not a direct observable. It is
shown that the isospin distribution of nucleons
at kinetic freezeout is binomial and factorized.
This leads to formulae for \sqrt (s_NN) gt 10GeV
that express the baryon number cumulants solely
in terms of proton number fluctuations, which are
experimentally observable.

Conclusion
The White Paper demonstrates the unique physics
potential of the NICA/MPD Complex. Broad
international resonance to the NICA White Paper
is an important step towards an international
collaboration for the creation of the NICA/MPD
and BM_at_N experiments. Physics in the NICA
energy range is rich and attractive!
