Determination of subrepresentations of the standard higher dimensional shearlet group
This paper is devoted to definition standard higher dimension shearlet group $ mathbb{S} = mathbb{R}^{+} times mathbb {R}^{n-1} times mathbb {R}^{n} $ and determination of square integrable subrepresentations of this group. Also we give a characterisation of admissible vectors associated to the Hilbert spaces corresponding to each su brepresentations.
متن کاملHigh-energy Unitarity and the Standard Model *
High-energy unitarity is argued to select a special version of QCD as the strong interaction. Electroweak symmetry breaking has to be due to a new sextet quark sector-that will produce large cross-section effects at the LHC. The sextet sector embeds, uniquely, in a massless SU (5) theory that potentially generates the states and interactions of the Standard Model within a bound-state S-Matrix. ...
متن کاملUnitarity of the Standard Model at the higgs’ resonance
We compute a unitarity bound for higgs mass using one–loop corrected s–wave partial amplitude for ZLZL → ZLZL scattering. We use the equivalence theorem and show that the higgs mass has to be less than ≈ 600 GeV in order to save the (perturbative) unitarity in the higgs’ resonance region. We also discuss about the validity of perturbation expansion in the symmetry breaking sector. 1 internet: s...
متن کاملCp-violation and Unitarity Triangle Test of the Standard Model
Phenomenological issues of the CP violation in the quark sector of the Standard Model are discussed. We consider quark mixing in the SM, standard and Wolfenstein parametrization of the CKM mixing matrix and unitarity triangle. We discuss the phenomenology of the CP violation in K0 L and B 0 d(B̄ 0 d)-decays. The standard unitarity triangle fit of the existing data is discussed. In appendix A we ...
متن کاملUnification of the Standard Model Via High-Energy Unitarity
High-energy unitarity is satisfied by adding a sextet quark doublet to QCD. The sextet sector produces electroweak symmetry breaking and is predicted to give large cross-section effects at the LHC. It embeds, uniquely, in a massless SU(5) theory whose bound-state S-Matrix, potentially, reproduces the Standard Model. Infra-red chirality transitions of the massless Dirac sea play an essential dyn...
