If no light Higgs boson exists, the interaction among the gauge bosons becomes strong at high energies (∼ 1TeV). The effects of strong electroweak symmetry breaking (SEWSB) could manifest themselves indirectly as anomalous couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings is presented looking at the hadronic deca...

We consider the effective two-Higgs-doublet potential with complex parameters, when the CP invariance is broken both explicitly and spontaneously. Diagonal mass term in the local minimum of the potential is constructed. For special case of the two-doublet Higgs sector of the minimal supersymmetric model, when CP invariance is violated by the Higgs bosons interaction with scalar quarks of the th...

We show how the entanglement in a wide range of continuous variable non-Gaussian states can be preserved against decoherence for long-range quantum communication through an optical fiber. We apply protection via decoherence-free subspaces and quantum dynamical decoupling to this end. The latter is implemented by inserting phase shifters at regular intervals inside the fiber, where is roughly th...

We investigate the relation between the rank I separable potential for the covariant Bethe-Salpeter equation and the one-boson-exchange potential. After several trials of the parameter choices, it turns out that it is not always possible to reproduce the phase-shifts calculated from a single term of the one-boson-exchange potential especially of the σ-exchange term, separately by the rank I sep...

Pseudo-Goldstone bosons couple with photons through a P and T violating interaction of the form L I = g aγγ aF˜F. Strong magnetic fields in rotating compact stars induce a non-zero E · B outside the stellar surface which acts as a source for the pseudo-scalar field. Pulsar signals propagating through this pseudo-scalar 'hair' suffer a differential time lag between the left and the right circula...

We show that a vibrational instability of the spectrum of weakly interacting quasilocal harmonic modes creates the maximum in the inelastic scattering intensity in glasses, the Boson peak. The instability, limited by anharmonicity, causes a complete reconstruction of the vibrational density of states ~DOS! below some frequency vc , proportional to the strength of interaction. The DOS of the new...

This paper is the fourth in a series devoted to the development of a rigorous renormalisation group method for lattice field theories involving boson fields, fermion fields, or both. The third paper in the series presents a perturbative analysis of a supersymmetric field theory which represents the continuous-time weakly self-avoiding walk on Zd. We now present an analysis of the relevant inter...

We examine the effects of pseudoscalar and pseudovector coupling of the p and h mesons in one-boson exchange models of the NN interaction using two approaches: time-ordered perturbation theory unitarized with the relativistic Lippmann-Schwinger equation, and a reduced Bethe-Salpeter approach using the Thompson equation. Contact terms in the one-boson exchange amplitudes in time-ordered perturba...

This article reports on a search for dark matter pair production in association with a Higgs boson decaying to a pair of bottom quarks, using data from 20.3 fb−1 of pp collisions at a center-of-mass energy of 8 TeV collected by the ATLAS detector at the LHC. The decay of the Higgs boson is reconstructed as a high-momentum bb̄ system with either a pair of small-radius jets, or a single large-radi...

The recent apparent observation [1, 2] of the Higgs boson [3, 4, 5, 6] has led to much interest in the popular claim that the Higgs boson (or better, the Higgs field) “gives mass” to those elementary particles that have it. Discuss how the de Broglie relations [7] for “matter waves” lead to a wave equation with a term that depends on mass, and that interpretation of this term as due to the inte...
