A Fermionic Top Partner: Naturalness and the LHC
Naturalness demands that the quadratic divergence of the one-loop top contribution to the Higgs mass be cancelled at a scale below 1 TeV. This can be achieved by introducing a fermionic (spin-1/2) top partner, as in, for example, Little Higgs models. In this paper, we study the phenomenology of a simple model realizing this mechanism. We present the current bounds on the model from precision el...
متن کاملNaturalness (final)
In the wake of David Lewis’s seminal paper ‘New Work for a Theory of Universals’ (1983), a certain use of the word ‘natural’ has become widespread in metaphysics and beyond. In this usage, properties can be classified as more or less natural, with perfectly natural properties as a limiting case. For example, Lewis would claim that being negatively charged is much more natural than being either ...
متن کاملElectroweak symmetry breaking in Higgs mechanism with composite operators and solution of naturalness
Introducing a source for a bi-local composite operator, we calculate its effective potential in the renormalization group of Standard Model with no involvement of technicolor. The potential indicates the breaking of electroweak symmetry below a scale M due to a nonzero vacuum expectation value of neutral component for the SU(2)-doublet operator at a scale Λ, fixed by the measured masses of gaug...
متن کاملTop-Bottom Splitting in Technicolor with Composite Scalars
We present a model of dynamical electroweak symmetry breaking in which the splitting between the top and bottom quark masses arises naturally. The W and Z masses are produced by a minimal technicolor sector, the top quark mass is given by the exchange of a weak-doublet technicolored scalar, and the other quark and lepton masses are induced by the exchange of a weak-doublet technicolor-singlet s...
متن کاملNatural Light: a Naturalness Bias in Lighting
A naturalness bias has been defined as ‘a preference for things perceived as natural’. This paper makes a first attempt at answering the question whether a naturalness bias exist in the context of lighting, and whether people’s sense of personal connection to nature and their beliefs towards different types of lighting affect its occurrence. This exploratory paper uses four studies to evaluate ...
