On the Leading ORder Hadronic Contribution to (g-2)_mu
Kim Maltman
Sum rule constraints dominated by the independent high-scale input, alpha_s(M_Z), are shown to be satisfied by I=1 spectral data from hadronic tau decays, but violated by the pre-2…
Universal coverings of Steinberg Lie algebras of small characteristic
Yun Gao, Shikui Shang
It is well-known that the second homology group $H_2(\st)$ of the Steinberg Lie algebra $\st$ is trivial when . In this paper, we will work out $H_2(\st)$ explicitly for $…
Measurement of the Isolated Photon Cross Section in p-pbar Collisions at sqrt{s}=1.96 TeV
D0 Collaboration
The cross section for the inclusive production of isolated photons has been measured in p anti-p collisions at sqrt{s}=1.96 TeV with the D0 detector at the Fermilab Tevatron Collid…
On some classes of Lindelöf Sigma-spaces
Wieslaw Kubis, Oleg Okunev, Paul J. Szeptycki
We consider special subclasses of the class of Lindelöf Sigma-spaces obtained by imposing restrictions on the weight of the elements of compact covers that admit countable networks…
Low-luminosity Active Galaxies and their Central Black Holes
Xiaoyi Dong, Michael M. De Robertis
Central black hole masses for 118 spiral galaxies representing morphological stages S0/a through Sc and taken from the large spectroscopic survey of Ho, Filippenko & Sargent (1997)…
The Hopf algebras of symmetric functions and quasisymmetric functions in non-commutative variables are free and cofree
Nantel Bergeron, Mike Zabrocki
We uncover the structure of the space of symmetric functions in non-commutative variables by showing that the underlined Hopf algebra is both free and co-free. We also introduce th…
