Unparticle as a field with continuously distributed mass
We point out that the notion of an unparticle, recently introduced by Georgi,
can be interpreted as a particular case of a field with continuously
distributed mass considered in ref.\cite{14}. We also point out that the
simplest renormalizable extension of the
Standard Model is the extension with the replacement of the U(1) gauge
propagator with .Comment: 6 pages, added references, corrected typo
Influence of singlet scalars on Higgs boson signal at LHC
We investigate a model of singlet scalars coupled to
Standard Model. We point out that for the case of maximal mixing between
singlet scalars and standard Higgs boson the Higgs boson production cross
section is smaller than the standard Higgs boson production by factor
, where N is the number of singlet scalar scalars. For the case
of big mixing Higgs boson could be nonobservable at LHC. However, there is also
a possibility for the observation of scalar singlets at LHC. As a
quasirealistic example we discuss a supersymmetric
electroweak model with an additional gauge singlet chiral superfield.Comment: 9 pages, latex, no figure
