Exact null tachyons from renormalization group flows
Allan Adams, Albion Lawrence, and Ian Swanson
We construct exact two-dimensional conformal field theories, corresponding to closed string tachyon and metric profiles invariant under shifts in a null coordinate, which can be constructed from any two-dimensional renormalization group flow. These solutions satisfy first order equations of motion i ... [Phys. Rev. D 80, 106005 (2009)] published Fri Nov 20, 2009.
Supersymmetry preserving mass deformation of [script N]=1 super Yang-Mills theory in D=2+1 dimensions
Abhishek Agarwal
We construct a massive non-Abelian [script N]=1 supersymmetric Yang-Mills theory on [openface R]. This is achieved by using a nonlocal gauge and a Poincare invariant mass term for gluons due to Nair. The underlying supersymmetry algebra is shown to be a noncentral extension of the Poincare algebra b ... [Phys. Rev. D 80, 105020 (2009)] published Fri Nov 20, 2009.
Baryon magnetic moments in large-N chiral perturbation theory
Ruben Flores-Mendieta
The baryon magnetic and transition magnetic moments are computed in heavy baryon chiral perturbation theory in the large-N limit, where N is the number of colors. One-loop nonanalytic corrections of orders m and mlnm are incorporated into the analysis, where contributions of both intermediate octet ... [Phys. Rev.

Measurement of the top quark mass in final states with two leptons
V. M. Abazov, B. Abbott, M. Abolins, B. S. Acharya, M. Adams et al. D0 Collaboration
We present measurements of the top quark mass (m) in t[overline t] candidate events with two final state leptons using 1 fb of data collected by the D0 experiment. Our data sample is selected by requiring two fully identified leptons or by relaxing one lepton requirement to an isolated track if at ... [Phys. Rev. D 80, 092006 (2009)] published Fri Nov 20, 2009.
On a CP anisotropy measurement in the Dalitz plot
I. Bediaga, I. I. Bigi, A. Gomes, G. Guerrer, J. Miranda et al.
We describe a novel use of the Dalitz plot to probe CP symmetry in three-body modes of B and D mesons. It is based on an observable inspired by astronomers' practice, namely the significance in the difference between corresponding Dalitz plot bins. It provides a model-independent mapping of local CP ... [Phys. Rev. D 80, 096006 (2009)] published Fri Nov 20, 2009.
S as a natural flavor symmetry for lepton mixing
Federica Bazzocchi and Stefano Morisi
Group theoretical arguments seem to indicate the discrete symmetry S as the minimal flavor symmetry compatible with tribimaximal neutrino mixing. We prove in a model-independent way that indeed S can realize exact tribimaximal mixing through different symmetry breaking patterns. We present two model ... [Phys. Rev. D 80, 096005 (2009)] published Thu Nov 19, 2009.
Factorization structure of gauge theory amplitudes and application to hard scattering processes at the LHC
Jui-yu Chiu, Andreas Fuhrer, Randall Kelley, and Aneesh V. Manohar
Previous work on electroweak radiative corrections to high-energy scattering using soft-collinear effective theory (SCET) has been extended to include external transverse and longitudinal gauge bosons and Higgs bosons. This allows one to compute radiative corrections to all parton-level hard scatter ... [Phys. Rev. D 80, 094013 (2009)] published Thu Nov 19, 2009.
Yukawa alignment in the two-Higgs-doublet model
Antonio Pich and Paula Tuzon
In multi-Higgs-doublet models the alignment in flavor space of the relevant Yukawa matrices guarantees the absence of tree-level flavor-changing couplings of the neutral scalar fields. We analyze the consequences of this condition within the two-Higgs-doublet model and show that it leads to a generi ... [Phys. Rev. D 80, 091702 (2009)] published Thu Nov 19, 2009.
Deformations of 3-algebras
Jose Miguel Figueroa-O'Farrill
We phrase deformations of n-Leibniz algebras in terms of the cohomology theory of the associated Leibniz algebra. We do the same for n-Lie algebras and for the metric versions of n-Leibniz and n-Lie algebras. We place particular emphasis on the case of n=3 and explore the deformations of 3-algebras ... [J. Math.

Asymptotically free four-Fermi theory in 4 dimensions at the z=3 Lifshitz-like fixed point
Avinash Dhar, Gautam Mandal, and Spenta R. Wadia
We show that a Nambu-Jona-Lasinio type four-fermion coupling at the z=3 Lifshitz-like fixed point in 3+1 dimensions is asymptotically free and generates a mass scale dynamically. This result is nonperturbative in the limit of a large number of fermion species. The theory is ultraviolet complete and ... [Phys. Rev. D 80, 105018 (2009)] published Tue Nov 17, 2009.
Violation of CP and T in semileptonic decays due to scalar interactions
G. Lopez Castro, L. Lopez-Lozano, and A. Rosado
Observing charge-parity (CP) or time-reversal (T) violations in the leptonic sector will give useful information to elucidate the nature of neutrinos. CP-violating couplings in charged leptonic currents carry out the weak phases necessary to break these symmetries. Here we study the interference of ... [Phys. Rev.

Shear viscosity and instability from third order Lovelock gravity
Xian-Hui Ge, Sang-Jin Sin, Shao-Feng Wu, and Guo-Hong Yang
We calculate the ratio of shear viscosity to entropy density for charged black branes in third order Lovelock theory. For chargeless black branes, the result turns out to be consistent with the prediction made by Brustein and Medved [Phys. Rev. D 79, 021901 (2009)].. We find that the third order Lov ... [Phys. Rev.

Effect of the gluon condensate on the holographic heavy quark potential
Youngman Kim, Bum-Hoon Lee, Chanyong Park, and Sang-Jin Sin
The gluon condensate is very sensitive to the QCD deconfinement transition since its value changes drastically with the deconfinement transition. We calculate the gluon condensate dependence of the heavy quark potential in AdS/CFT to study how the property of the heavy quarkonium is affected by a re ... [Phys. Rev.

Anomalies, unparticles, and Seiberg duality
Jamison Galloway, John McRaven, and John Terning
We calculate triangle anomalies for fermions with noncanonical scaling dimensions. The most well-known example of such fermions (aka unfermions) occurs in Seiberg duality where the matching of anomalies (including mesinos with scaling dimensions between 3/2 and 5/2) is a crucial test of duality. By ... [Phys. Rev. D 80, 105017 (2009)] published Mon Nov 16, 2009.
Gauge threshold corrections for local type-IIB/F-theory GUTs
Joseph P. Conlon and Eran Palti
We study gauge threshold corrections for local grand unified theory models in IIB/F-theory. Consistency with holomorphy requirements of supergravity and the Kaplunovsky-Louis formula implies that the unification scale is enhanced by the bulk radius R from the string scale to M=RM. We argue that the ... [Phys. Rev. D 80, 106004 (2009)] published Mon Nov 16, 2009.
Correlation classes on the landscape: To what extent is string theory predictive?
Keith R. Dienes and Michael Lennek
In light of recent discussions of the string landscape, it is essential to understand the degree to which string theory is predictive. We argue that it is unlikely that the landscape as a whole will exhibit unique correlations amongst low-energy observables, but rather that different regions of the ... [Phys. Rev.

Crossing symmetry and modular invariance in conformal field theory and S duality in gauge theory
Dimitri V. Nanopoulos and Dan Xie

Poincare invariance in an auxiliary spacetime is found in the Lagrangian version of the path integral formulation. This invariance is co ... [Phys. Rev.

Light Higgs boson scenario in the supersymmetric seesaw model
Masaki Asano, Takayuki Kubo, Shigeki Matsumoto, and Masato Senami
It is demonstrated that the light Higgs boson scenario, in which the lightest Higgs mass is less than the LEP bound, m>114.4 GeV, is consistent with the supersymmetric seesaw model. With the assumptions of the universal right-handed neutrino mass and the hierarchical mass spectrum of the ordinary n ... [Phys. Rev. D 80, 095017 (2009)] published Mon Nov 16, 2009.

Johannes Blumlein, Sebastian Klein, and Beat Todtli
In deep-inelastic processes the heavy flavor Wilson coefficients factorize for Q>>m into the light-flavor Wilson coefficients of the corresponding process and the massive operator matrix elements (OMEs).

Hyperquarks and bosonic preon bound states
Michael L. Schmid and Alfons J. Buchmann
In a model in which leptons, quarks, and the recently introduced hyperquarks are built up from two fundamental spin-(1/2) preons, the standard model weak gauge bosons emerge as preon bound states. In addition, the model predicts a host of new composite gauge bosons, in particular, those responsible ... [Phys. Rev. D 80, 095020 (2009)] published Mon Nov 16, 2009.
