Hadron Spectroscopy
Using a large data sample recorded with the Belle detector
at the KEKB asymmetric energy e^+ e^- collider,
we report new results on charmonium-like states
produced in gamma-gamma collisions including studies of
final states with multiple
kaons. We also report updates on other new particles
and resonances recently observed in B decays by Belle.

With growing datasets collected by the CDF II experiment, studies of the
spectroscopy of mesons containing heavy quarks becomes more exciting. The
CDF experiment has good capabilities in both charm and bottom sector. This
capability allowed also to contribute to the study of the Zoo of states
called X,Y,Z. In this area we present a recent update of the mass
measurement of X(3872). The...

Hadron Spectroscopy
In most recent analyses of D^0 D-bar^0 pi^0 decays of the X(3872), these events were assumed to come from D^{*0} D-bar^0 or D^0 D-bar^{*0} followed by the decay of the D^{*0} or D-bar^{*0}. Given this assumption, every D^0 D-bar^0 pi^0 event near the D^{*0} D-bar^0 threshold is assigned an invariant mass above the threshold. Such an analysis necessarily yields a mass for the X(3872) that is...

Hadron Spectroscopy
Fermilab operates the world's most intense antiproton source. Newly proposed experiments can use those antiprotons either parasitically during Tevatron Collider running or after the Tevatron Collider finishes in about 2011. For example, the annihilation of 8 GeV antiprotons might make the world's most intense source of tagged D^0 mesons, and thus the best near-term opportunity to study charm...

Hadron Spectroscopy
Weakly decaying bottom baryons can in principle be clearly reconstructed from
their decays into J/psi or other charmed hadrons. However, their
properties like lifetimes and branching fractions have long been quoted
only as averages over all states, as the only directly observed b-baryon
was the Lambda_b. Only in year 2007, the two Tevatron experiments observed
the Xi_b, and recently the...
