Leptogenesis in Realistic SO(10) Models

Mohapatra a,S.Nasria,YueZhangb a Department of Physics, University of Maryland, College Park, MD 20742, USA b Institute for Theoretical Physics, Peking University, Beijing, China Received 16 May 2007; received in revised form 4 June 2007; accepted 10 June 2007 Available online 13 June 2007 Editor: T. Yanagida Abstract We study the origin of baryonic matter via leptogenesis in realistic SO(10) models, in particular, in a new lopsided mass matrix model introduced recently by three of the authors. It is shown that the model generates sufficient baryon asymmetry in addition to fitting to fermion masses and mixing. We compare this result with other realistic SO(10) models. © 2007 Elsevier B.V. All rights reserved. 1. Introduction One of the most fundamental questions in modern cosmology is where the baryon number asymmetry in today’s Universe comes from. It is an attractive idea to assume that it arises dynamically in a symmetric big-bang model through C and CP violating processes out of thermal equilibrium. Of the several proposals that use this scenario, leptogenesis [1] has emerged as one of the most interesting scenarios for baryon generation. Here the baryon number is produced through the so-called sphaleron processes from a residual lepton number density left over from an early stage of the universe through lepton number violating decays of right-handed neutrinos. Such connection is extremely interesting since the same heavy right-handed neutrinos are also important ingredients for understanding the small left-handed neutrino masses through the so-called see-saw mechanism [2]. -

Understanding the energy depositions from backgrounds or calibration sources in these detectors is very important. The program of BambooMC is created to perform the Geant4-based Monte Carlo simulation, providing reference information for the experiments. We introduce the design and features of BambooMC in this report. The running of the program depends on a configuration file, which combines different detectors, event generators, physics lists and analysis packs together in one simulation. -

Polyharmonic homogenization, rough polyharmonic splines and sparse super-localization. Houman Owhadi,∗ Lei Zhang,y Leonid Berlyand z June 13, 2013 Abstract We introduce a new variational method for the numerical homogenization of di- vergence form elliptic, parabolic and hyperbolic equations with arbitrary rough (L1) coefficients. Our method does not rely on concepts of ergodicity or scale-separation but on compactness properties of the solution space and a new variational approach to homogenization. The approximation space is generated by an interpolation basis (over scattered points forming a mesh of resolution H) minimizing the L2 norm of the source terms; its (pre-)computation involves minimizing O(H−d) quadratic (cell) problems on (super-)localized sub-domains of size O(H ln(1=H)). The result- ing localized linear systems remain sparse and banded. The resulting interpolation basis functions are biharmonic for d ≤ 3, and polyharmonic for d ≥ 4, for the op- erator − div(a∇·) and can be seen as a generalization of polyharmonic splines to differential operators with arbitrary rough coefficients. The accuracy of the method (O(H) in energy norm and independent from aspect ratios of the mesh formed by the scattered points) is established via the introduction of a new class of higher- order Poincar´einequalities. The method bypasses (pre-)computations on the full domain and naturally generalizes to time dependent problems, it also provides a natural solution to the inverse problem of recovering the solution of a divergence form elliptic equation from a finite number of point measurements.

Flux Norm Approach to Finite Dimensional Homogenization Approximations with Non-Separated Scales and High Contrast
Arch. Rational Mech. Anal. 198 (2010) 677–721 Digital Object Identifier (DOI) 10.1007/s00205-010-0302-1 Flux Norm Approach to Finite Dimensional Homogenization Approximations with Non-Separated Scales and High Contrast Leonid Berlyand & Houman Owhadi Communicated by C. Le Bris Abstract We consider linear divergence-form scalar elliptic equations and vectorial equa- tions for elasticity with rough (L∞(), ⊂ Rd ) coefficients a(x) that, in particular, model media with non-separated scales and high contrast in material properties. While the homogenization of PDEs with periodic or ergodic coefficients and well separated scales is now well understood, we consider here the most general case of arbitrary bounded coefficients. For such problems, we introduce explicit and optimal finite dimensional approximations of solutions that can be viewed as a theoretical Galerkin method with controlled error estimates, analogous to classical homogenization approximations. In particular, this approach allows one to ana- lyze a given medium directly without introducing the mathematical concept of an family of media as in classical homogenization. We define the flux norm as the L2 norm of the potential part of the fluxes of solutions, which is equivalent to the usual H 1-norm. We show that in the flux norm, the error associated with approximating, in a properly defined finite-dimensional space, the set of solutions of the aforementioned PDEs with rough coefficients is equal to the error associated with approximating the set of solutions of the same type of PDEs with smooth coefficients in a standard space (for example, piecewise polynomial). We refer to this property as the transfer property. -

The areas of research concentration of the faculty cover a broad spectrum of the applied mathematical sciences. Areas of scholarly activity include: Optimization, Statistics, Probability, Discrete Mathematics, Numerical Analysis, Operations Research, Computational Biology and Computational Mathematics. In 1999, as evidence of the department’s reputation, we were awarded a prestigious five year, one and a half million dollar grant from the Colorado Commission for Higher Education. This was the Center of Excellence Grant, for excellence in research and graduate education; unfortunately budget cuts forced a complete elimination of the funding in the final two years of the grant. It is the department mission to provide a quality education to all students at all levels, from service courses through the highest level of graduate instruction. During this year, the department awarded 20 undergraduate degrees, 11 Master’s and 3 Ph.
