  • A class of Hamiltonians for a three-particle fermionic system at unitarity 
    Correggi, Michele; Dell'Antonio, Gianfausto; Finco, Domenico; Michelangeli, Alessandro; Teta, Alessandro (2015-05-15)
    We consider a quantum mechanical three-particle system made of two identical fermions of mass one and a different particle of mass $m$, where each fermion interacts via a zero-range force with the different particle. In ...
  • Classification of complete N=2 supersymmetric theories in 4 dimensions 
    Cecotti, Sergio; Vafa, Cumrun (SISSA, 2011-03-30)
    We define the notion of a complete N=2 supersymmetric theory in 4 dimensions as a UV complete theory for which all the BPS central charges can be arbitrarily varied as we vary its Coulomb branch parameters, masses, ...
  • Closed Bosonic String Field Theory at Quintic Order II: Marginal Deformations and Effective Potential 
    Moeller, Nicolas (2007-05-31)
    We verify that the dilaton together with one exactly marginal field, form a moduli space of marginal deformations of closed bosonic string field theory to polynomial order five. We use the results of this successful check ...
  • Closed Bosonic String Field Theory at Quintic Order: Five-Tachyon Contact Term and Dilaton Theorem 
    Moeller, Nicolas (2006-10-11)
    We solve the geometry of the closed string field theory five-point vertex. Our solution is calculated in terms of quadratic Strebel differentials which are found numerically all over the relevant subspace of the moduli ...
  • Cohesive fracture with irreversibility: quasistatic evolution for a model subject to fatigue 
    Crismale, Vito; Lazzaroni, Giuliano; Orlando, Gianluca (SISSA, 2016-07-19)
    In this paper we prove the existence of quasistatic evolutions for a cohesive fracture on a prescribed crack surface, in small-strain antiplane elasticity. The main feature of the model is that the density of the energy ...
  • Cohomology of Skew-holomorphic lie algebroids 
    Bruzzo, Ugo; Rubtsov, Vladimir (2010-03-08)
    We introduce the notion of skew-holomorphic Lie algebroid on a complex manifold, and explore some cohomologies theories that one can associate to it. Examples are given in terms of holomorphic Poisson structures of various sorts.
  • A comment on the measurement of neutrino masses in beta-decay experiments 
    Bilenky, Samoil M.; Mateev, Matey D.; Petcov, Serguey T. (2006-05-11)
    We discuss the physics potential of future tritium beta-decay experiments having a sensitivity to a neutrino mass ~\sqrt{|\Delta m^{2}_{23}|}~5x10^{-2} eV. The case of three-neutrino mixing is analised. A negative result ...
  • Comments on the non-conformal gauge theories dual to Ypq manifolds 
    Brini, Andrea; Forcella, Davide (2006-05-30)
    We study the infrared behavior of the entire class of Y(p,q) quiver gauge theories. The dimer technology is exploited to discuss the duality cascades and support the general belief about a runaway behavior for the whole ...
  • Compactness by maximality 
    Zagatti, Sandro (2011)
    We derive a compactness property in the Sobolev space $W^{1,1}(\O)$ in order to study the Dirichlet problem for the eikonal equation \begin{displaymath} \begin{cases} \ha |\n u(x)|^2 - a(x) = 0 & \ \textrm{in} \ \O\cr ...
  • Compactness for a class of integral functionals with interacting local and non-local terms 
    Braides, Andrea; Dal Maso, Gianni (2022-12-20)
    We prove a compactness result with respect to 􀀀-convergence for a class of integral functionals which are expressed as a sum of a local and a non-local term. The main feature is that, under our hypotheses, the local part ...
  • Comparison of two methods for the definition of the infinite time limit of the time evolution operator in scattering theory 
    Toth, Gabor Zsolt (2009-04-22)
    A comparison of the methods of averaging and adiabatic switching for the definition of the infinite time limit of the time evolution operator in scattering theory is presented. The focus is on certain basic features which ...
  • The complete one-loop spin chain for N=2 Super-Yang-Mills 
    Di Vecchia, Paolo; Tanzini, Alessandro (2007-10-29)
    We show that the complete planar one-loop mixing matrix of the N=2 Super Yang--Mills theory can be obtained from a reduction of that of the N=4 theory. For composite operators of scalar fields, this yields an anisotropic ...
  • Complex Friedrichs systems and applications 
    Antonić, Nenad; Burazin, Krešimir; Crnjac, Ivana; Erceg, Marko (2017-01)
    Recently, there has been a significant development of the abstract theory of Friedrichs systems in Hilbert spaces (Ern, Guermond & Caplain, 2007; Antoni´c & Burazin, 2010), and its applications to specific problems in ...
  • The composite operator T-Tbar in sinh-Gordon and a series of massive minimal models 
    Delfino, Gesualdo; Niccoli, Giuliano (2006-04-12)
    The composite operator T\bar{T}, obtained from the components of the energy-momentum tensor, enjoys a quite general characterization in two-dimensional quantum field theory also away from criticality. We use the form factor ...
  • Computing Amplitudes in topological M-theory 
    Bonelli, Giulio; Tanzini, Alessandro; Zabzine, Maxim (2006-12-07)
    We define a topological quantum membrane theory on a seven dimensional manifold of $G_2$ holonomy. We describe in detail the path integral evaluation for membrane geometries given by circle bundles over Riemann surfaces. ...
  • Conifold geometries, matrix models and quantum solutions 
    Bonelli, Giulio; Bonora, Loriano; Ricco, Antonio (2005)
    This paper is a continuation of hepth/0507224 where open topological B-models describing D-branes on 2-cycles of local Calabi--Yau geometries with conical singularities were studied. After a short review, the paper expands ...
  • Conifold geometries, topological strings and multi-matrix models 
    Bonelli, Giulio; Bonora, Loriano; Ricco, Antonio (2005)
    We study open B-model representing D-branes on 2-cycles of local Calabi-Yau geometries. To this end we work out a reduction technique linking D-branes partition functions and multimatrix models in the case of conifold ...
  • Connecting Low Energy Leptonic CP-violation to Leptogenesis 
    Pascoli, Silvia; Petcov, Serguey T.; Riotto, Antonio (2006-12-11)
    It was commonly thought that the observation of low energy leptonic CP-violating phases would not automatically imply the existence of a baryon asymmetry in the leptogenesis scenario. This conclusion does not generically ...
  • Conservative solutions of the Camassa-Holm Equation on the real line 
    Fonte, Massimo (2005)
    In this paper we construct a global, continuous flow of solutions to the Camassa-Holm equation on the space H1(R). In a previous paper [2], A. Bressan and the author constructed spatially periodic solutions, whereas in ...
  • Consistent de Sitter String Vacua from Kahler Stabilization and D-term uplifting 
    Parameswaran, Susha L.; Westphal, Alexander (2007-03-02)
    In this note, we review our construction of de Sitter vacua in type IIB flux compactifications, in which moduli stabilization and D-term uplifting can be combined consistently with the supergravity constraints. Here, the ...
