Running couplings and operator mixing in the gravitational corrections to coupling constants
Running couplings operator mixing
2010/12/23
The use of a running coupling constant in renormalizable theories is well known, but the implementation of this idea for effective field theories with a dimensional coupling constant is in general le...
Strange Quark Mass and $1^{++}$ Nonet Singlet-Octet Mixing Angle
Strange Quark Mass $1^{++}$ Nonet Singlet-Octet Mixing Angle
2011/1/7
We compute the strange quark mass from the analysis of the $f_1(1420)-f_1(1285)$ mass difference QCD sum rule, where the operator-product-expansion series is up to dimension six and to ${\cal O}(\alph...
Stretching and folding versus cutting and shuffling: An illustrated perspective on mixing and deformations of continua
Fluid Dynamics (physics.flu-dyn) Chaotic Dynamics (nlin.CD)
2010/11/10
We compare and contrast two types of deformations inspired by mixing applications -- one from the mixing of fluids (stretching and folding), the other from the mixing of granular matter (cutting and s...
Dark matter and a new gauge boson through kinetic mixing
Hidden gauge symmetry Kinetic mixing Thermal dark matter
2010/11/16
We consider a hidden sector model of dark matter which is charged under a hidden U(1)X gauge symmetry. Kinetic mixing of U(1)X with the Standard Model hypercharge U(1)Y is allowed to provide communica...

Thermohaline Mixing: Does It Really Govern the Atmospheric Chemical Composition of Low-Mass Red Giants?
stars abundances — stars evolution — stars interiors
2010/11/12
First results of our 3D numerical simulations of thermohaline convection driven by 3He burning in a low-mass RGB star at the bump luminosity are presented. They confirm our previous conclusion that th...
We present improved bounds on the CP-violating phase J/ s and on the decay-width difference of the neutral B0 s meson system ob-tained by the CDF experiment at the Tevatron collider . 
Higgs triplets at like-sign linear colliders and neutrino mixing
Higgs triplets like-sign linear colliders neutrino mixing
2011/1/5
We study the phenomenology of the type-II seesaw model at a linear e−e− collider. We show
that the process e−e− ! α−β− (α, β = e, μ, τ being charged leptons) media...
A Shift from Democratic to Tri-bimaximal Neutrino Mixing with Relatively Large theta_{13}
Democratic Tri-bimaximal Neutrino Mixing Relatively Large theta_{13}
2011/1/5
Recent neutrino oscillation data hint that the smallest neutrino mixing angle 13 is possible to lie in the range 5◦ < ∼ 13 <∼12◦.
MHD Simulations of Parker Instability Undergoing Cosmic-Ray Diffusion: Effect of the Initial Equilibrium Conditions on Mixing
cosmic rays magnetohydrodynamics instability numerical simulation
2010/11/9
Parker instability arises from the presence of magnetic fields in a plasma such as the interstellar medium (ISM),wherein the magnetic buoyant pressure expels the gas and causes the gas to move along t...

Using the X-ray Morphologies of Young Supernova Remnants to Constrain Explosion Type, Ejecta Distribution, and Chemical Mixing
methods data analysis supernova remnants techniques image processing X-rays ISM
2010/11/10
Supernova remnants (SNRs) are a complex class of sources, and their heterogeneous nature has
hindered the characterization of their general observational properties. To overcome this challenge,in thi...

2011/1/6
We study the effect of squark-generation mixing on production and decays of squarks and gluinos at LHC in the Minimal Supersymmetric Standard Model (MSSM). We show that the mixing effects can be very ...

Tight Bounds for Mixing of the Swendsen-Wang Algorithm at the Potts Transition Point

2010/11/19
We study two widely used algorithms for the Potts model on rectangular subsets of the hypercubic lattice Z^d - heat bath dynamics and the Swendsen-Wang algorithm - and prove that, under certain circu...
