  • Hochmuth, K.A.; Petcov, Serguey T.; Rodejohann, Werner (2007-08-09)
    We consider corrections to vanishing U_{e3} and maximal atmospheric neutrino mixing originating from the relation U = U_ell^dagger U_nu, where U is the PMNS mixing matrix and U_ell (U_nu) is associated with the diagonalization ...
  • Bruzzo, Ugo; Markushevich, Dimitri; Tikhomirov, Alexander (2010-09-08)
    We construct a compactification $M^{\mu ss}$ of the Uhlenbeck-Donaldson type for the moduli space of slope stable framed bundles. This is a kind of a moduli space of slope semistable framed sheaves. We show that there ...
  • Giuricin, Giuliano; Mardirossian, Fabio; Mezzetti, Marino; Persic, Massimo; Salucci, Paolo (SISSA, 1993-08-11)
    We present an observational mass function ranging from galaxies to massive galaxy clusters, derived from direct dynamical mass estimates. Our mass function shows, in the low-mass range of galaxies and groups, a behaviour ...
  • Bianchini, Stefano; Bonicatto, Paolo (2017)
  • Bilenky, Samoil M.; Grimus, Walter; Schwetz, Thomas (2006-02-22)
    There are claims in the literature that in neutrino oscillations and oscillations of neutral kaons and B-mesons the oscillation phase differs from the standard one by a factor of two. We reconsider the arguments leading ...
  • Benini, Francesco; Canoura, Felipe; Cremonesi, Stefano; Nunez, Carlos; Ramallo, Alfonso V. (2007-08-30)
    Using AdS/CFT, we study the addition of an arbitrary number of backreacting flavors to the Klebanov-Witten theory, making many checks of consistency between our new Type IIB plus branes solution and expectations from field ...
  • Argurio, Riccardo; Bertolini, Matteo; Ferretti, Gabriele; Mariotti, Alberto (2010-07-23)
    Gaugino screening, the absence of next-to-leading order corrections to gaugino masses, is a generic feature of gauge mediation models of supersymmetry breaking. We show that in a specific class of models, known as semi-direct ...
  • Spinolo, Laura (2006-02-02)
    We consider the 2 x 2 parabolic systems [] on a domain (t, x) [] with Dirichlet boundary conditions imposed at x = 0 and at x = l. The matrix A is assumed to be in triangular form and strictly hyperbolic, and the boundary ...
  • Dal Maso, Gianni (2006-04-18)
    We present some recent existence results for the variational model of crack growth in brittle materials proposed by Francfort and Marigo in 1998. These results, obtained in collaboration with Francfort and Toader, cover ...
  • Crismale, Vito; Lazzaroni, Giuliano (SISSA, 2015)
    Employing the technique of vanishing viscosity and time rescaling, we show the exis- tence of quasistatic evolutions for elastoplastic materials with incomplete damage affecting both the elastic tensor and the plastic yield ...
  • Acharya, Bobby Samir; Benini, Francesco; Valandro, Roberto (2007-01-31)
    Warped models, originating with the ideas of Randall and Sundrum, provide a fascinating extension of the standard model with interesting consequences for the LHC. We investigate in detail how string theory realises such ...
  • Chialva, Diego; Shiu, Gary; Underwood, Bret (2006-03-23)
    We investigate in some quantitative details the viability of reheating in multi-throat brane inflationary scenarios by estimating and comparing the time scales for the various processes involved. We also calculate within ...
  • Dal Maso, Gianni; Lucardesi, Ilaria (2015-10)
    Given a bounded open set $\Omega \subset \mathbb R^d$ with Lipschitz boundary and an increasing family $\Gamma_t$, $t\in [0,T]$, of closed subsets of $\Omega$, we analyze the scalar wave equation $\ddot{u} - div (A \nabla ...
  • Tasso, Emanuele (SISSA, 2018-11)
    In this paper we formulate and study the system of elastodynamics on domains with arbitrary growing cracks. This includes homogeneous Neumann conditions on the crack sets and mixed general Dirichlet-Neumann conditions on ...
  • Tilli, Paolo; Zucco, Davide (SISSA, 2014)
    We study a shape optimization problem for the first eigenvalue of an elliptic operator in divergence form, with non constant coefficients, over a fixed domain $\Omega$. Dirichlet conditions are imposed along $\partial\Omega$ ...
  • Bonelli, Giulio; Maruyoshi, Kazunobu; Tanzini, Alessandro (SISSA, 2011-12-15)
    We study N=2 supersymmetric SU(2) gauge theories coupled to non-Lagrangian superconformal field theories induced by compactifying the six dimensional A_1 (2,0) theory on Riemann surfaces with irregular punctures. These ...
  • Exirifard, Ghasem (2006-07-21)
    All the linear alpha-prime corrections in the compactification of the critical Heterotic string theory on T^6 are computed for a BPS static spherical four dimensional dyonic black hole representing a wrapped fundamental ...
