Probing New Physics with Astrophysical Neutrinos

چکیده

We review the prospects for probing new physics with neutrino astrophysics. High energy neutrinos provide an important means of accessing physics beyond the electroweak scale. Neutrinos have a number of advantages over conventional astronomy and, in particular, carry information encoded in their flavor degree of freedom which could reveal a variety of exotic neutrino properties. We also outline ways in which neutrino astrophysics can be used to constrain dark matter properties, and explain how neutrino-based limits lead to a strong general bound on the dark matter total annihilation cross-section. Talk given at Neutrino 2008, Christchurch, New Zealand, 26-31 May 2008.

Probing new physics with long-lived charged particles produced by atmospheric and astrophysical neutrinos

As suggested by some extensions of the Standard Model of particle physics, dark matter may be a super-weakly interacting lightest stable particle, while the next-to-lightest particle (NLP) is charged and meta-stable. One could test such a possibility with neutrino telescopes, by detecting the charged NLPs produced in highenergy neutrino collisions with Earth matter. We study the production of c...

Probing Neutrino Dark Energy with Extremely High-Energy Cosmic Neutrinos

Recently, a new non-Standard Model neutrino interaction mediated by a light scalar field was proposed, which renders the big-bang relic neutrinos of the cosmic neutrino background a natural dark energy candidate, the so-called Neutrino Dark Energy. As a further consequence of this interaction, the neutrino masses become functions of the neutrino energy densities and are thus promoted to dynamic...

Theoretically Palatable Flavor Combinations of Astrophysical Neutrinos.

The flavor composition of high-energy astrophysical neutrinos can reveal the physics governing their production, propagation, and interaction. The IceCube Collaboration has published the first experimental determination of the ratio of the flux in each flavor to the total. We present, as a theoretical counterpart, new results for the allowed ranges of flavor ratios at Earth for arbitrary flavor...

Explanation for the low flux of high-energy astrophysical muon neutrinos.

There has been some concern about the unexpected paucity of cosmic high-energy muon neutrinos in detectors probing the energy region beyond 1 PeV. As a possible solution we consider the possibility that some exotic neutrino property is responsible for reducing the muon neutrino flux at high energies from distant sources; specifically, we consider (i) neutrino decay and (ii) neutrinos being pseu...

High Energy Astrophysical Tau Neutrinos: The Expectations

A search for high energy astrophysical tau neutrinos will not only yield quite useful information about some of the highest energy phenomenons occurring in the present universe related to the origin of observed high energy gamma rays and ultra high energy cosmic rays but also can possibly probe physics beyond standard model of particle physics. The representative extra terrestrial sources of hi...
