We study the role that future detection of neutrino burst from a galactic supernova can play in reconstruction mass spectrum. consider all possible 3$\nu$ and flavor spectra which describe solar atmospheric data. For each these we find observable effects conversions both matter star earth. show studies electron anineutrino as well observations neutral current will allow us (i) to identify solution, (ii) determine type hierarchy (normal or inverted) (iii) probe mixing $|U_{e3}|^2$ values low...

Collective oscillations of supernova neutrinos swap the spectra f(nu(e))(E) and f(nu[over ](e))(E) with those another flavor in certain energy intervals bounded by sharp spectral splits. This phenomenon is far more general than previously appreciated: typically one finds or swaps accompanying splits nu nu[over ] channels for both inverted normal neutrino mass hierarchies. Depending on an instability condition, develop around crossings (energies where f(nu(e))=f(nu(x)), ](e))=f(nu[over ](x))...
Neutrino-neutrino interactions in dense neutrino streams, like those emitted by a core-collapse supernova, can lead to self-induced flavor conversions. While this is nonlinear phenomenon, the onset of these conversions be examined through standard stability analysis linearized equations motion. The problem reduced linear eigenvalue equation that involves density, energy spectrum, angular distribution, and matter density. In single-angle case, we reproduce previous results use them identify...
This report contains the results of Workshop on CKM Unitarity Triangle, held at CERN 13-16 February 2002 to study determination matrix from available data K, D, and B physics. is a coherent document with chapters covering elements tree level decays K meson mixing global fits unitarity triangle parameters. The impact future measurements also discussed.
Neutrinos and antineutrinos emitted from a core collapse supernova interact among themselves, giving rise to collective flavor conversion effects that are significant near the neutrinosphere. We develop formalism analyze these in complete three-flavor framework. It naturally generalizes spin-precession analogy three flavors is capable of analytically describing phenomena like vacuum/Mikheyev-Smirnov-Wolfenstein (MSW) oscillations, synchronized bipolar spectral split. Using formalism, we...
A few seconds after bounce in a core-collapse supernova, the shock wave passes density region corresponding to resonant neutrino oscillations with 'atmospheric' mass difference. The transient violation of adiabaticity condition manifests itself an observable modulation signal from future galactic supernova. In addition propagation effects that were previously studied, reverse forms when supersonically expanding neutrino-driven wind collides slower earlier supernova ejecta. This implies for...
In early 2010, the Long-Baseline Neutrino Experiment (LBNE) science collaboration initiated a study to investigate physics potential of experiment with broad set different beam, near- and far-detector configurations. Nine initial topics were identified as scientific areas that motivate construction long-baseline neutrino very large far detector. We summarize justification for each topic estimated performance detector reference report also on optimized beam parameters capability proposed Near...
We identify a class of U(1) X models which can explain the R K anomaly and neutrino mixing pattern, by using bottom-up approach. The different X-charges lepton generations account for universality violation required to . In addition three right-handed neutrinos needed Type-I seesaw mechanism, these minimal only introduce an additional doublet Higgs singlet scalar. While former helps in reproducing quark structure, latter gives masses new gauge boson Z ′. Our approach determines all particles...
The prompt ${\ensuremath{\nu}}_{e}$ burst from a core-collapse supernova is subject to both matter-induced flavor conversions and strong neutrino-neutrino refractive effects. For the lowest-mass progenitors, leading O-Ne-Mg core supernovae, matter density profile can be so steep that usual Mikheyev-Smirnov-Wolfenstein effects occur within dense-neutrino region close neutrino sphere. In this case ``split'' occurs in emerging spectrum, i.e., survival probability shows steplike feature. We...
New physics models that increase the decay rate of ${B}_{s}\ensuremath{\rightarrow}{\ensuremath{\tau}}^{+}{\ensuremath{\tau}}^{\ensuremath{-}}$ contribute to absorptive part ${B}_{s}--{\overline{B}}_{s}$ mixing, and may enhance $\ensuremath{\Delta}{\ensuremath{\Gamma}}_{s}$ all way up its current experimental bound. In particular, model with a scalar leptoquark can lead significant violation expectation...
Collective neutrino flavor transformations deep inside a supernova are sensitive to the mass hierarchy even at extremely small values of theta_(13). Exploiting this effect, we show that comparison antineutrino signals from galactic in two megaton class water Cherenkov detectors, one which is shadowed by Earth, will enable us distinguish between hierarchies if sin(2)theta_(13) < or approximately 10(-5), where long baseline experiments would be ineffectual.
The proposed ICAL experiment at INO aims to identify the neutrino mass hierarchy from observations of atmospheric neutrinos, and help improve precision on mixing parameters. While design is primarily optimized measure muon momentum, it also capable measuring hadron energy in each event. Although measured with relatively lower resolution, nevertheless contains crucial information event, which may be extracted when taken concomitant data. We demonstrate that by adding direction sensitivity...

Using GEANT4 modeling detector interactions atmospheric neutrinos with target nuclei are simulated. hadrons propagating through it investigated using hit multiplicity in active elements. charged pions fixed studied first, followed by average produced neutrino events simulated NUANCE event...
Neutrino self-interactions are known to lead non-linear collective flavor oscillations in a core-collapse supernova. We point out new possible effects of non-standard (NSSI) neutrinos on conversions two-flavor framework. show that, for single-energy neutrino-antineutrino ensemble, instability is generated even normal hierarchy large enough NSSI. Using toy model the neutrino spectra, we that flavor-preserving NSSI pinching spectral swaps, while flavor-violating cause swaps develop away from...
If an ultralight scalar interacts with the electromagnetic fields of a compact rotating star, then long-range field is developed outside star. The Coulomb-like profile equivalent to effective charge on In binary star system, scalar-induced would result in force between stars, acting as mediator. scalar-photon interactions modify Maxwell's equations for vacuum, resulting modified dispersion relation. This could be observed apparent redshift photons emitted by such sources. also induce...
Atmospheric neutrinos, through their weak interactions, can serve as an independent tool for exploring the internal structure of Earth. The information obtained would be complementary to that provided by seismic and gravitational measurements. Earth matter effects in neutrino oscillations depend upon energy neutrinos electron density distribution they encounter during journey Earth, hence, used probe inner In this contribution, we demonstrate how well atmospheric experiment, such iron...

The neutrino oscillations in Earth matter introduce modulations the supernova spectra. These can be exploited to identify presence of effects on spectra, which would enable us put a limit value mixing angle θ13 and whether mass hierarchy is normal or inverted. We demonstrate how identified at single detector without prior assumptions about flavour-dependent source using Fourier transform `inverse-energy' spectrum signal. explore factors affecting efficiency this method, find that energy...
