  • no scale n 4 supergravity coupled to yang mills the scalar potential and super Higgs effect
    Physics Letters B, 2003
    Co-Authors: M. A. Lledo, Riccardo Dauria, S Ferrara, Silvia Vaula
    Abstract:

    Abstract We derive the scalar potential of the effective theory of type IIB orientifold with 3-form fluxes turned on in presence of non-Abelian brane coordinates. N =4 supergravity predicts a positive semidefinite potential with vanishing cosmological constant in the vacuum of commuting coordinates, with a classical moduli space given by three radial moduli and three RR scalars which complete three copies of the coset ( U (1,1+ n )/ U (1)⊗ U (1+ n )), together with 6 n D3-branes coordinates, n being the rank of the gauge group G . Implications for the super-Higgs Mechanism are also discussed.

  • gauge independent brout englert Higgs Mechanism and yang mills theory with a gauge invariant gluon mass term
    European Physical Journal C, 2018
    Co-Authors: Keiichi Kondo
    Abstract:

    For the Yang–Mills theory coupled to a single scalar field in the fundamental representation of the gauge group, we present a gauge-independent description of the Brout–Englert–Higgs Mechanism by which massless gauge bosons acquire their mass. The new description should be compared with the conventional gauge-dependent description relying on the spontaneous gauge symmetry breaking due to a choice of the non-vanishing vacuum expectation value of the scalar field. In this paper we focus our consideration on the fundamental scalar field which extends the previous work done for the Yang–Mills theory with an adjoint scalar field. Moreover, we show that the Yang–Mills theory with a gauge-invariant mass term is obtained from the corresponding gauge-scalar model when the radial degree of freedom (length) of the scalar field is fixed. The result obtained in this paper is regarded as a continuum realization of the Fradkin–Shenker continuity and Osterwalder–Seiler theorem for the complementarity between Higgs regime and Confinement regime which was given in the gauge-invariant framework of the lattice gauge theory. Moreover, we discuss how confinement is investigated through the gauge-independent Brout–Englert–Higgs Mechanism by starting with the complementary gauge-scalar model.

  • gauge independent Higgs Mechanism and the implications for quark confinement
    Epj Web of Conferences, 2017
    Co-Authors: Keiichi Kondo
    Abstract:

    We propose a gauge-invariant description for the Higgs Mechanism by which a gauge boson acquires the mass. We do not need to assume spontaneous breakdown of gauge symmetry signaled by a non-vanishing vacuum expectation value of the scalar field. In fact, we give a manifestly gauge-invariant description of the Higgs Mechanism in the operator level, which does not rely on spontaneous symmetry breaking. For concreteness, we discuss the gauge-Higgs models with U (1) and SU (2) gauge groups explicitly. This enables us to discuss the confinement-Higgs complementarity from a new perspective.

  • scherk schwarz reduction of d 5 special and quaternionic geometry
    arXiv: High Energy Physics - Theory, 2004
    Co-Authors: Laura Maria Andrianopoli, Sergio Ferrara, M. A. Lledo
    Abstract:

    We give the N=2 gauged supergravity interpretation of a generic D=4, N=2 theory as it comes from generalized Scherk-Schwarz reduction of D=5, N=2 (ungauged) supergravity. We focus on the geometric aspects of the D=4 data such as the general form of the scalar potential and masses in terms of the gauging of a ``flat group''. Higgs and super-Higgs Mechanism are discussed in some detail.
