Borexino is a large volume liquid scintillator detector mainly devoted to the study of solar neutrinos. It is located under the Gran Sasso mountain in Italy and has been taking data since 2007. Thanks to its low background and its large mass, Borexino has been able of performing an almost complete spectroscopy of solar neutrinos.
In this talk I will focus on the latest result published by...

In 2011, Double Chooz became the first reactor-based experiment to indicate a nonzero value of the neutrino mixing parameter $\theta_{13}$. This observation was made with a single detector located approximately 1 km from the two cores of the Chooz Nuclear Power Plant in northeastern France. Since then, the Double Chooz collaboration has increased the precision of its single-detector...

The Daya Bay reactor neutrino experiment announced the discovery of a non-zero value of $\sin^22\theta_{13}$ with significance better than 5 $\sigma$, in 2012. The experiment is continuing to improve the precision of $\sin^22\theta_{13}$ and explore other physics topics.
In this talk, I will show the current oscillation and mass-squared difference results which is base on the combination of...

In this talk I will discuss the origin of the reactor neutrino anomaly, the physics issues involved, and the uncertainties. Since the suggestion of an anomaly, a second puzzle has arisen with the reactor antineutrino spectra, namely the appearance of a shoulder in the spectra measured at Daya Bay, RENO, and Double Chooz. The shoulder is predicted within some nuclear database analyses, but...

The T2K ("Tokai to Kamioka") experiment is a long-baseline neutrino oscillation experiment in Japan. A beam of muon neutrinos or muon anti-neutrinos is produced at the Japan Proton Accelerator Research Complex (J-PARC) in Tokai. The unoscillated neutrino flux is measured by the near detector complex 280 m from the proton target, and the oscillated neutrino flux is measured by the far detector,...

We consider classes of standard model (SM) extensions with a scalar representation (charged singlets, triplet and/or 5-plet) and three generation fermionic representations (right handed neutrinos, triplets or 5-plets). In these models, the neutrino masses are generated at three loops, which provide an explanation for their smallness, and the lightest neutral fermion, is a dark matter...

I will study the simplest extension of the SM that can account for neutrino masses: the Type-I seesaw with 2 and 3 right-handed neutrinos. The model introduces a New Physics scale, M, which is often assumed to be much larger than the electroweak scale. However, it is presently unconstrained and the light neutrino masses and mixing can be generated for any value of M above eV. Paying special...

Discovery of the third mixing angle theta13 has opened up the possibility of discovering the neutrino mass hierarchy. There are a number of near future experiments proposed (some already funded) which aim at determining the mass hierarchy. In this talk I will review the prospects of discovering the neutrino mass hierarchy in the next generation neutrino experiments.

EXO-200 is an experiment searching for neutrinoless double beta decay using a time projection chamber with 175 kg of liquid xenon enriched in $^{136}$Xe. The observation of this process would indicate that the neutrino is a Majorana fermion and lepton number is not a conserved quantity, and would allow for the calculation of the absolute mass of the neutrino. The low radioactive background...

Confirmation of neutrino oscillations in different experiments has established the massive character of neutrino and served as a strong evidence to look beyond the well-accepted standard model of particles. Most of the unified theories thus evolved are based on Majorana character of neutrinos. At present most promising and only experiment to settle the Majorana/Dirac nature of neutrino that is...

We discuss the various incarnations of a gauged B-L symmetry: 1) as an unbroken symmetry, it features Dirac neutrinos, neutrinogenesis to create the baryon asymmetry, and a potentially light Z' boson; 2) broken by two units, we obtain the standard case of Majorana neutrinos, seesaw and thermal leptogenesis; 3) broken by four units, we find Dirac neutrinos with lepton-number-violating...

Fermilab's MINERvA experiment is designed to make precision measurements of neutrino scattering cross sections on a variety of materials. After introducing the MINERvA detector, I will explain why these measurements are so important to the current neutrino program. I will then describe several recently published results that are already being applied by the neutrino community to improve their...
