Results on Charmonium-like States at BaBar
We present recent results on charmonium and charmonium-like states from the
BaBar B-factory located at the PEP-II asymmetric energy storage
ring at the SLAC National Accelerator Laboratory.Comment: 7 pages, 5 Figures, Proceeding of the Conference "QCD@Work -

Diffractive Phenomena at Tevatron
Preliminary results from the D0 experiment on jet production with rapidity
gaps in collisions are presented. A class of dijet events with a
forward rapidity gap is observed at center-of-mass energies = 1800
GeV and 630 GeV. The number of events with rapidity gaps at both center-of-mass
energies is significantly greater than the expectation from multiplicity
fluctuations and is consistent with a hard single diffractive process. A class
of events with two forward gaps and central dijets are also observed at 1800
GeV. This topology is consistent with hard double pomeron exchange. We also
present proposed plans for extending these analysis into Run II through the use
of a forward proton detector.Comment: plain tex, 5 pages, 2 figure
Weinhold'length in an isochoric thermodynamic system at constant heat capacity
The purpose of this paper is to study thermodynamic length of an isochoric
two dimensional thermodynamic system with constant heat capacity. We find that
length is related to the heat flow into the substance. We give examples of
Ideal gas and Van der Waals gas
