Large N anomalous dimensions for large operators in Leigh-Strassler deformed SYM
Robert de Mello Koch, Jeff Murugan, Nkululeko Nokwara
We study the large N anomalous dimensions of operators in a Leigh-Strassler deformation of N=4 super Yang-Mills theory. The operators that we study have a bare dimension of order N…
Disk Stability and Neutral Hydrogen as a Tracer of Dark Matter
Gerhardt R. Meurer, Zheng Zheng, W. J. G. de Blok
We derive the projected surface mass distribution Sigma_M for spherically symmetric mass distributions having an arbitrary rotation curve. For a galaxy with a flat rotation curve a…
Bright radio emission from an ultraluminous stellar-mass microquasar in M31
Matthew J. Middleton, James C. A. Miller-Jones, Sera Markoff +34
A subset of ultraluminous X-ray sources (those with luminosities < 10^40 erg/s) are thought to be powered by the accretion of gas onto black holes with masses of ~5-20 M_solar, pro…
Particle-antiparticle asymmetry from magnetogenesis through the Landau mechanism
D. Carcamo, Ashok Das, J. Gamboa +1
Motivated by string theory an extension of the Landau problem to quantum field theory is considered. We show that the commutator between momenta of the fields violates Lorentz and…
The meson and chiral symmetry restoration and deconfinment at finite temperature QCD
C. A. Dominguez, M. Loewe, Y. Zhang
We consider the light-quark axial-vector current correlator in the framework of thermal QCD sum rules to: (a) find a relation between chiral-symmetry restoration and deconfinement,…
The 2MASS Tully-Fisher Survey : Mapping the Mass in the Universe
T. Hong, L. Staveley-Smith, K. Masters +5
The 2MASS Tully-Fisher Survey (2MTF) aims to measure Tully-Fisher (TF) distances for all bright inclined spirals in the 2MASS Redshift Survey (2MRS) using high quality HI widths an…
