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…
Wick rotations in 3D gravity: ML(H2)-spacetimes
Riccardo Benedetti, Francesco Bonsante
"Ends of hyperbolic 3-manifolds should support canonical Wick Rotations, so they realize effective interactions of their ending globally hyperbolic spacetimes of constant curvature…
The Toric Phases of the Y^{p,q} Quivers
Sergio Benvenuti, Amihay Hanany, Pavlos Kazakopoulos
We construct all connected toric phases of the recently discovered quivers and show their IR equivalence using Seiberg duality. We also compute the R and global U(1) char…
Search for a Charged Partner of the X(3872) in the B Meson Decay B --> X- K, X- --> J/psi pi- pi0
B. Aubert, BaBar Collaboration
We search for a charged partner of the X(3872) in the decay B --> X- K, X- --> J/psi pi- pi0, using 234 million BBbar events collected at the Y(4S) resonance with the BaBar detecto…
Shot noise in charge and magnetization currents of a quantum ring
F. Cavaliere, F. Haupt, R. Fazio +1
The shot noise in a quantum ring, connected to leads, is studied in the presence of electron interactions in the sequential tunneling regime. Two qualitatively different noise corr…
Spectral projections for the twisted Laplacian
Herbert Koch, Fulvio Ricci
The twisted Laplacian in the d=2n dimensional Euclidean space has the spectrum n+2k, k a nonnegative integer. We find sharp asymptotic bounds of the norm of the projection to the e…
