Neutrino-electron scatterings (nu - e) are purely leptonic processes with robust standard model predictions. Their measurements can therefore provide constraints to physics beyond the standard model. Noncommutative (NC) field theories modify space-time commutation relations, and allow neutrino electromagnetic couplings at the tree level. Their contribution to the neutrino-electron scattering cross section was derived. Constraints were placed on the NC scale parameter Lambda(NC) from nu - e experiments with reactor and accelerator neutrinos. The most stringent limit of Lambda(NC) > 3.3 TeV at 95% confidence level improves over the direct bounds from collider experiments.

Constraints on nonstandard neutrino interactions and unparticle physics with (v) over bar (e)-e(-) scattering at the Kuo-Sheng nuclear power reactor
Deniz, M.; Bilmiş, Selçuk; Yildirim, I. O.; Li, H. B.; Li, J.; Liao, H. Y.; Lin, C. W.; Lin, S. T.; Serin, Meltem; Singh, V.; Wong, H. T.; Wu, S. C.; Yue, Q.; Zeyrek, Mehmet Tevfik; Zhou, Z. Y. (2010-08-05)
Neutrino-electron scatterings are purely leptonic processes with robust standard model (SM) predictions. Their measurements can therefore provide constraints to physics beyond SM. The (nu) over bar (e) - e data taken at the Kuo-Sheng Reactor Neutrino Laboratory were used to probe two scenarios: nonstandard neutrino interactions (NSI) and unparticle physics. New constraints were placed on the NSI parameters (epsilon(eL)(ee), epsilon(eR)(ee) ), (epsilon(eL)(e mu), epsilon(eR)(e mu)), and (epsilon(eL)(e tau), ...
Double-lepton polarization asymmetries and branching ratio of the B -> gamma l(+)l(-) transition in universal extra dimension
AZİZİ, KAZEM; Pak, N. K.; ŞİRVANLI, BERİN BELMA (2012-02-01)
We study the radiative dileptonic B ->gamma l(+)l(-) transition in the presence of a universal extra dimension in the Applequist-Cheng-Dobrescu model. In particular, using the corresponding form factors calculated via light cone QCD sum rules, we analyze the branching ratio and double lepton polarization asymmetries related to this channel and compare the results with the predictions of the standard model. We show how the results deviate from predictions of the standard model at lower values of the compacti...
The effects of non-universal extra dimensions on the radiative lepton flavor decays mu -> e gamma and tau ->mu gamma in the two Higgs doublet model
Iltan, EO (2004-08-01)
We study the effect of non-universal extra dimensions on the branching ratios of the lepton flavor violating processes mu --> egamma and tau --> mugamma in the general two Higgs doublet model. We observe that these effects are small for a single extra dimension, however, in the case of two extra dimensions there is a considerable enhancement in the additional contributions.
The mu -> e gamma and tau ->mu gamma decays with the inclusion of Lorentz and CPT violating effects
Iltan, EO (2003-06-01)
We study the Lorentz and CPT violating effects on the branching ratio and the CP violating asymmetry of the lepton flavor violating interactions mu --> egamma and tau --> mugamma, in the model III version of the two Higgs doublet model. Here we consider that the Lorentz and CPT violating effects exist in the QED part of the interactions and enter into expressions in the lepton propagators and in the lepton-photon vertex. We observe that there exists a non-zero CP asymmetry. However, the Lorentz and CPT viol...
The form factors existing in the b -> sg* decay and the possible CP violating effects in the noncommutative standard model
Iltan, EO (2002-11-01)
We study the form factors appearing in the inclusive decay b --> sg*, in the framework of the noncommutative standard model. Here g* denotes the virtual gluon. We get additional structures and the corresponding form factors in the noncommutative geometry. We analyse the dependencies of the form factors to the parameter p Theta k where p (k) are the four momenta of incoming (outgoing) b quark (virtual gluon g*), Theta is a parameter which measures the noncommutativity of the geometry. We see that the form fa...
