Unparticle physics in single top signals
(EPL Association, European Physical Society, 2008) Alan, Ahmet Turan; Pak, N. K.; Şenol, Abdulkadir
We study the single production of top quarks in e(+)e(-), ep and pp collisions in the context of unparticle physics through the Flavor Violating (FV) unparticle vertices and compute the total cross-sections for single top production as functions of scale dimension d(u). We find that among all, LHC is the most promising facility to probe the unparticle physics via single top quark production processes. Copyright (C) EPLA, 2008.
Unparticle physics in top pair signals at the LHC and ILC
(Epl Association, European Physical Society, 2008) Alan, Ahmet Turan; Pak, N. K.
We study the effects of unparticle physics in the pair productions of top quarks at the LHC and ILC. By considering vector, tensor and scalar unparticle operators, as appropriate, we compute the total cross-sections for pair production processes depending on the scale dimension d(U). We find that the existence of unparticles would lead to measurable enhancements on the SM predictions at the LHC. In the case of ILC this may become two orders of magnitude larger than that of SM, for smaller values of d(U), a very striking signal for unparticles. Copyright (C) EPLA, 2008
