Top and Higgs Mass from Cancellation Conditions

چکیده
The success of the electroweak gauge theory [1] has led to a great revival of Quantum Field Theory. By this, however, many theorists do not mean a theory of quantized interacting fields [2]. One rather derives observable results from the "Green's functions" specified by Feynman's integration over classical fields [3], All problems are thus reduced to the choice of the action, which then is evaluated in standard ways (numerically [4] or by perturbation [5])For us who still employ quantized interacting fields, a critical question is how these (and their products) can exist. Is it essential to construct [6] everything with mathematical rigor? Can supergravity remedy the divergencies, or will more recent ideas [7] be needed? Should we admit new physical structures such as a realistic cutoff [8]? Here let us explore the last possibility, since other avenues have been widely discussed. The foundations of fields quantized in our sense shall include:

Little Higgs Searches at Lhc on Behalf the Atlas Collaboration
A new method of solving the hierarchy problem in the SM has been proposed. This method leads to the so-called " Little Higgs " models. The ATLAS experiment at LHC has undertaken studies of the new particles predicted by these model: a heavy top quark, heavy gauge bosons and additional Higgs bosons. Simulations of their decays have been carried out. The sensitivity of the ATLAS experiment to dis...
متن کاملA Quirky Little Higgs Model
We consider an extra dimensional model where the quadratically divergent top loop contribution to the Higgs mass is cancelled by an uncolored heavy “top quirk” charged under a different SU(3) gauge group. The cancellation is enforced by bulk gauge symmetries. Thus we have an unusual type of little Higgs model which has some quirky signatures. The top partner in this model could be identified at...
متن کاملQuasi-supersymmetry in Top Sector of the Standard Model
We show the existence of quasi-supersymmetry as formulated by Nambu in the top-sector of the standard model. We present the explicit form of the quasi-supersymmetric charge. We also deduce,like Nambu, a quasi supersymmetric mass relation which is the same as suggested by Veltman. PACS Index : 11.30Pb, 12.60Nz Typeset using REVTEX 1 Higgs fields provide the only missing link in the standard mode...
متن کاملRemarks on the upper bounds on the Higgs boson mass from triviality.
We study the effects of the one-loop matching conditions on Higgs boson and top quark masses on the triviality bounds on the Higgs boson mass using βλ with corrected twoloop coefficients. We obtain quite higher results than previous ones and observe that the triviality bounds are not nearly influenced by varying top quark mass over the range measured at CDF and D0. The effects of typo errors in...
متن کاملRadiative electroweak symmetry breaking in a Little Higgs model
Abstract: We present a new Little Higgs model, motivated by the deconstruction of a five-dimensional gauge-Higgs model. The approximate global symmetry is SO(5)0×SO(5)1, breaking to SO(5), with a gauged subgroup of [SU(2)0L × U(1)0R] × O(4)1, breaking to SU(2)L×U(1)Y . Radiative corrections produce an additional small vacuum misalignment, breaking the electroweak symmetry down to U(1)EM. Novel ...
متن کاملDynamical Electroweak Symmetry Breaking in SO(5)×U(1) Gauge-Higgs Unification with Top and Bottom Quarks
An SO(5)×U(1) gauge-Higgs unification model in the Randall-Sundrum warped space with top and bottom quarks is constructed. Additional fermions on the Planck brane make exotic particles heavy by effectively changing boundary conditions of bulk fermions from those determined by orbifold conditions. Gauge couplings of a top quark multiplet trigger electroweak symmetry breaking by the Hosotani mech...
