We present a comprehensive discussion of the ground-state properties dilute D-dimensional Bose gas interacting with few static impurities. Assuming short-ranged character boson-impurity interaction, we calculated energy three- and two-dimensional systems one two impurities immersed.

We show that in realistic constituent quark models based on a two-body confinement interaction color states appear in the middle of the experimentally known spectrum. To avoid this situation we implement a three-body confinement interaction, introduced on an algebraic basis, into a semirela-tivistic version of the Goldstone boson exchange constituent quark model and by solving the Faddeev equat...

We explore the use of polarized e+/e− beams and/or the information on final state decay lepton polarizations in probing the interaction of the Higgs boson with a pair of vector bosons. A model independent analysis of the process e+e− → f f̄H, where f is any light fermion, is carried out through the construction of observables having identical properties under the discrete symmetry transformation...

We implement the SU(5)/SO(5) littlest Higgs theory in a slice of 5D Anti-de Sitter space bounded by a UV brane and an IR brane. In this model, there is a bulk SU(5) gauge symmetry that is broken to SO(5) on the IR brane, and the Higgs boson is contained in the Goldstones from this breaking. All of the interactions on the IR brane preserve the global symmetries that protect the Higgs mass, but a...

In the empirically sensible limit in which QCD, t-quark Yukawa, and scalar-fieldinteraction coupling constants dominate all other Standard-Model coupling constants, we sum all leading-logarithm terms within the perturbative expansion for the effective potential that contribute to the extraction of the Higgs boson mass via radiative electroweak symmetry breaking. A Higgs boson mass of 216 GeV em...

The study of the spin-parity and tensor structure of the interactions of the recently discovered Higgs boson is performed using the H → ZZ; Zγ ; γ γ → 4l, H → WW → lνlν, and H → γγ decay modes. The full data set recorded by the CMS experiment during the LHC run 1 is used, corresponding to an integrated luminosity of up to 5.1 fb−1 at a center-of-mass energy of 7 TeVand up to 19.7 fb−1 at 8 TeV....

We consider the extended electroweak gauge group SU(2) 1 ×SU(2) 2 ×U(1) Y where the first and second families of fermions couple to SU(2) 1 while the third family couples to SU(2) 2. Bounds based an precision electroweak observables and heavy gauge boson searches are placed on the new parameters of the theory. The extra gauge bosons can be as light as about a TeV and can be discovered at future...

We compute the Higgs mass in a model for the electroweak interactions based on a confining theory. This model is related to the standard model by the complementarity principle. A dynamical effect due to the large typical scale of the Higgs boson shifts its mass above that of the W-bosons. We obtain mH = 129.6 GeV. supported by the Deutsche Forschungsgemeinschaft, DFG-No. FR 412/27-1, email:calm...

We extend the scope of full configuration interaction quantum Monte Carlo (FCIQMC) to be applied coupled fermion-boson hamiltonians, alleviating a priori truncation in boson occupation which is necessary for many other wave function based approaches tractable. Detailing required algorithmic changes efficient excitation generation, we apply FCIQMC two contrasting settings. The first sign-problem...
