The authors' main claim In this scenario, with 2 Higgs doublets, we show that the decay of charged Higgs into {\em left-handed} charged lepton (say \tau) and right-handed neutrino can be significantly enhanced, with O(1) branching ratio, due to the large number of Kaluza-Klein states of the right-handed neutrino.

The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; .

In models with large extra dimensions and TeV scale quantum gravity, small (Dirac) neutrino masses can be obtained naturally if the right-handed neutrino propagates in the extra dimensions. In this scenario, with 2 Higgs doublets, we show that the decay of charged Higgs into {\em left-handed} charged lepton (say \tau) and right-handed neutrino can be significantly enhanced, with O(1) branching ratio, due to the large number of Kaluza-Klein states of the right-handed neutrino. Since \tau's from the standard decay of charged Higgs are {\em right-handed}, the above novel charged Higgs decay can provide a distinctive signature of these models at hadron/lepton colliders. Similarly, top quark decays to b \mu^+ \nu, b \tau^+ \nu through virtual charged Higgs can be enhanced.
