Abstract: We investigate the impact of light (∼ eV) sterile neutrinos in the long-baseline experiment T2K. We show that, within the 3+1 scheme, for mass-mixing parameters suggested by the short-baseline anomalies, the interference among the sterile and the atmospheric oscillation frequencies induces a new term in the νµ → νe transition probability, which has the same order of magnitude of the standard 3-flavor solar-atmospheric interference term. We show, for the first time, that current T2K data, taken together with th… Show more

“…We include the 4-flavor effects both in the ν µ → ν e appearance channel and in the ν µ → ν µ disappearance channel. We have found that, for the ν µ → ν µ disappearance channel, the survival probability is very close to the 3-flavor case, in agreement with the analytical considerations made in [19]. We consider the true value of sin 2 2θ 13 to be 0.085 (see table 1) to generate the data and keep it fixed in the fit expecting that the Daya Bay experiment would be able to measure θ 13 with a very high-precision (∼ 3% relative precision at 1σ C.L.)…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…( 7) (proportional to s 2 13 ) and the amplitude of the two standard interference terms (which are both proportional to s 13 ). A comparison of our results with those presented in [1,2] shows that the 68% and 90% bounds on δ 14 are slightly weaker, despite the improved statistics accumulated in the LBL data. This is due to having taken into account the uncertainty on θ 14 and θ 24 , which in [1,2] were both fixed to sin 2 θ 14 = sin 2 θ 24 = 0.025.…”

“…Therefore, in contrast to the vacuum case, in matter, the flavor conversion is sensitive to the two parameters θ 34 and δ 34 . Concerning the ν µ → ν e appearance probability, this behavior has been already pointed out in the analytical treatment presented in [6] (see the appendix therein), and successively noticed in the numerical simulations performed in [25].…”
