news feature On the trail of the neutrino Huge arrays of detectors now have these ghostly particles CHAMBERS NEUTRINO OBSERVATORY/R. SUDBURY in their sights — but will what they see lead physicists to rethink the standard model? Dan Falk investigates. n the subatomic zoo, few particles are as elusive as the neutrino. The Universe is Iawash with them, but they slide through most forms of matter with ease. Billions have passed through your body since you started reading this article. By one estimate, the average neutrino could travel for 1,000 light-years through solid matter before being stopped. This reluctance to interact with matter makes neutrinos difficult to detect. But, almost half a century after they were first spotted, neutrinos have become the focus of intense study. Exciting results from existing detectors, together with plans for new detec- tor projects, promise to make this a busy decade for neutrino hunters. The Sudbury Neutrino Observatory (SNO) in Ontario is poised to illuminate the physics of neutrinos produced by the Sun, and a new detector in Antarctica is making Full house: the detector at Sudbury Neutrino Observatory can detect all three flavours of neutrino. progress towards studying neutrinos from deep space — a first step towards building a particles.

Chapter 1 High-Energy Astrophysical Neutrinos
July 9, 2018 21:42 ws-rv9x6 Book Title trisep_halzen_061918 page 1 Chapter 1 High-Energy Astrophysical Neutrinos Francis Halzen Wisconsin IceCube Particle Physics Center UW{Madison, Madison, WI USA [email protected] Chargeless, weakly-interacting neutrinos are ideal astronomical messen- gers because they travel through space without scattering, absorption, or deflection. They provide the only unobstructed view of cosmic accelera- tors. But this weak interaction also makes them notoriously difficult to detect, leading to neutrino observatories requiring large-scale detectors. The IceCube experiment discovered PeV-energy neutrinos originating beyond the Sun, with energies bracketed by those of TeV-energy gamma rays and EeV-energy extragalactic cosmic rays. In this chapter, we dis- cuss the IceCube neutrino telescope, the status of the observation of cosmic neutrinos, and what neutrinos can tell us about the nonthermal Universe. Besides the search for the sources of Galactic and extragalactic cosmic rays, the scientific missions of IceCube and similar instruments under construction in the Mediterranean Sea and Lake Baikal include the observation of Galactic supernova explosions, the search for dark matter, and the study of neutrinos themselves. 1 July 9, 2018 21:42 ws-rv9x6 Book Title trisep_halzen_061918 page 2 2 Francis Halzen Contents 1.

Astronomy and Astrophysics with Neutrinos
IceCube: An Instrument for Neutrino Astronomy Francis Halzen1 and Spencer R. Klein2, 3 1Department of Physics, University of Wisconsin, 1150 University Avenue, Madison WI 53706 2Nuclear Science Division, Lawrence Berkeley National Laboratory, Berkeley, CA, 94720 3Department of Physics, University of California, Berkeley, CA, 94720 Abstract Neutrino astronomy beyond the Sun was first imagined in the late 1950s; by the 1970s, it was realized that kilometer-scale neutrino detectors were required. The first such instrument, IceCube, is near completion and taking data. The IceCube project transforms a cubic kilometer of deep and ultra-transparent Antarctic ice into a particle detector. A total of 5,160 optical sensors are embedded into a gigaton of Antarctic ice to detect the Cherenkov light emitted by secondary particles produced when neutrinos interact with nuclei in the ice. Each optical sensor is a complete data acquisition system, including a phototube, digitization electronics, control and trigger systems and LEDs for calibration. The light patterns reveal the type (flavor) of neutrino interaction and the energy and direction of the neutrino, making neutrino astronomy possible. The scientific missions of IceCube include such varied tasks as the search for sources of cosmic rays, the observation of Galactic supernova explosions, the search for dark matter, and the study of the neutrinos themselves. These reach energies well beyond those produced with accelerator beams. The outline of this review is as follows: • Neutrino Astronomy and Kilometer-Scale Detectors • High-Energy Neutrino Telescopes: Methodologies of Neutrino Detection • IceCube Hardware • High-Energy Neutrino Telescopes: Beyond Astronomy • Future Projects I. Introduction The Technology Soon after the 1956 observation of the neutrino1, the idea emerged that it represented the ideal astronomical messenger. -

Ignarra Submitted to the Department of Physics on August 29, 2014, in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Physics Abstract Tension among recent short baseline neutrino experiments has pointed toward the possible need for the addition of one or more sterile (non-interacting) neutrino states into the existing neutrino oscillation framework. This thesis first presents the moti- vation for sterile neutrino models by describing the short-baseline anomalies that can be addressed with them. This is followed by a discussion of the phenomenology of these models. The MiniBooNE experiment and results are then described in detail, particularly the most recent antineutrino analysis. This will be followed by a discus- sion of global fits to world data, including the anomalous data sets. Lastly, future experiments will be addressed, especially focusing on the MicroBooNE experiment and light collection studies. In particular, understanding the degradation source of TPB, designing the TPB-coated plates for MicroBooNE and developing lightguide collection systems will be discussed. We find an excess of events in the MiniBooNE antineutrino mode results consistent with the LSND anomaly, but one that has a different energy dependence than the low- energy excess reported in neutrino mode. -
