Sharp upper bounds on the number of the scattering poles
Plamen Stefanov
For various compactly supported perturbations of the Laplacian in odd dimensions , we prove a sharp upper bound of the resonance counting function of the type $N(r) \le A…
Brane-worlds and theta-vacua
S. Khlebnikov, M. Shaposhnikov
Reductions from odd to even dimensionalities ( or ), for which the effective low-energy theory contains chiral fermions, present us with a mismatch between ultravio…
Measurement of the J/Psi Meson and b-Hadron Production Cross Sections in ppbar Collisions at sqrt s = 1960 GeV
D. Acosta, CDF Collaboration
We present a new measurement of the inclusive and differential production cross sections of mesons and -hadrons in proton-antiproton collisions at GeV. The…
The Role of Grain Boundaries in Determining the Transport Properties in Magnetite
David C. Mertens, W. Montfrooij, R. J. McQueeney +2
We present magnetoresistance and Hall-effect measurements on single crystal magnetite Fe3O4 close to the Verwey transition Tv = 123.8 K. We show that the formation of grain boundar…
A Possible Detection of M31* with Chandra
M. R. Garcia, B. F. Williams, F. Yuan +5
Two independent sets of Chandra and HST images of the nuclear region of M31 allow registration of X-ray and optical images to 0.1''. This registration shows that none of the bright…
On the Validity of the Parabolic Effective-Mass Approximation for the Current-Voltage Calculation of Silicon Nanowire Transistors
Jing Wang, Anisur Rahman, Avik Ghosh +2
This paper examines the validity of the widely-used parabolic effective-mass approximation for computing the current-voltage (I-V) characteristics of silicon nanowire transistors (…
