On neutrino masses via CPT violating Higgs interaction in the Standard Model
Masud Chaichian, Kazuo Fujikawa, Anca Tureanu
The Lorentz invariant violation by using non-local interactions is naturally incorporated in the Higgs coupling to neutrinos in the Standard Model, without spoiling the basic…
Noncommutativity of Space and Rotation of Polarization of Light in a Background Magnetic Field
M. Chaichian, M. M. Sheikh-Jabbari, A. Tureanu
Recently the PVLAS collaboration has reported the observation of rotation of polarization of light propagating in a background magnetic field. In this letter we explore the possibi…
Single sneutrino production at hadron colliders
Masud Chaichian, Anindya Datta, Katri Huitu +2
We study the production of a single sneutrino in association with one or two -quarks at hadron colliders, in the framework of an R-parity violating supersymmetric model. We find…
Kaluza-Klein decomposition and gauge coupling unification in orbifold GUTs
Masud Chaichian, Archil Kobakhidze
We discuss Kaluza-Klein (KK) decomposition in 5-dimensional (5D) field theories with orbifold compactification. Kinetic terms localized at orbifold fixed points, which are inevitab…
Radion and Higgs mixing at the LHC
Masud Chaichian, Anindya Datta, Katri Huitu +1
We study the resonance production of radions and Higgs via gluon-gluon fusion in the Randall-Sundrum model with Higgs-curvature mixing at the LHC. We find that radion can be detect…
Radions in a collider
M. Chaichian, K. Huitu, A. Kobakhidze +1
We study the resonance production of radions via fusion in the Randall-Sundrum model. We find that the cross section of the process in the mode of a linear collider (LC)…
On Quadratic Divergences and the Higgs Mass
Masud Chaichian, Ricardo Gonzalez Felipe, Katri Huitu
The quadratic divergences in the scalar sector of the standard model are considered. Since the divergences are present also in the unbroken theory, a natural scale for the divergen…
TOP-INDUCED ELECTROWEAK BREAKING IN THE MINIMAL SUPERSYMMETRIC STANDARD MODEL
M. Chaichian, P. Chiappetta, J. -M. Gerard +2
Severe constraints on parameters of the minimal supersymmetric standard model follow from a dynamical electroweak symmetry breaking mechanism dominated by top and stop loops. In pa…
