Neutrino Physics
Poster
The majority of neutrino oscillation experiments have obtained evidence for neutrino oscillations that are compatible with the three-flavor model. Explaining anomalous results from short-baseline experiments, such as LSND and MiniBooNE, in terms of neutrino oscillations requires the existence of sterile neutrinos. The search for sterile neutrino mixing conducted in NOvA uses a long baseline of...

An essential part of new physics searches at the Large Hadron Collider at CERN involves event classification, or distinguishing signal decays from one of its many background look-alikes. Traditional techniques have relied on reconstructed particle candidates and their physical attributes. However, such reconstructed data are the result of a long, potentially lossy process of forcing the raw...

The next galactic core-collapse supernova will deliver a wealth of neutrinos which for the first time we are well-situated to measure. These explosions produce neutrinos with energies between 10 and 100 MeV over a period of tens of seconds. Galactic supernovae are relatively rare events, occurring with a frequency of just a few per century. It is therefore essential that all neutrino...

The IsoDAR (Isotope Decay-At-Rest) experiment aims to explore physics beyond the standard model by searching for anomalous neutrino oscillations indicative of sterile neutrinos. The experiment requires a primary beam of H2+ ions to be accelerated to an energy of 60 MeV/amu at a current of 5 mA, which will be accomplished by using a high-power compact cyclotron. One of the challenges in this...

Seasonal variations of cosmic ray muons have been well-measured by
a number of underground experiments at a variety of overburdens and
it has been found that the rate of muons increases in the summer and
decreases in the winter. This is understood from the properties of
the atmosphere as the temperature varies. But with
large statistics the seasonal variation of multiple muons was...

DUNE is an experiment aimed at determining the mass hierarchy of neutrinos and measuring parity violation in the neutrino sector. The ProtoDUNE detector is a prototype Liquid Argon (LAr) TPC for the DUNE far detector and will be operated at CERN to primarily study hadronic interactions in LAr at the few GeV energy scale.
Due to the operation of ProtoDUNE in a beamline near the surface, the...

SuperCDMS SNOLab is using low energy threshold Si/Ge detectors for dark
matter direct searches. One mode of operation for the experiment runs detectors in a
high-voltage-biased mode, to use Neganov-Luke Amplification.
Understanding the ionization yield of low-energy nuclear recoils is
essential for interpreting dark matter search data taken in this mode. We present two

In the universe, there are several sources that produce very energetic cosmic rays that interact with the Earth’s atmosphere and create new low energy particles. These particles can be electrically charged and neutral. There are different methods to detect them, according to its interaction with a medium such as the ionization of a material and Cerenkov radiation, among others. An obtained...

The goals of the Deep Underground Neutrino Experiment (DUNE) at Fermi Lab, is to
precisely measure neutrino and antineutrino oscillation properties to determine if
charge-parity (CP) symmetry is violated in the lepton sector, thus providing a possible
explanation for the matter-antimatter asymmetry in the universe, and to measure the
neutrino mass ordering. To maximize the...

NOvA is a neutrino oscillation experiment which probes the neutrino CP-violating phase and mass ordering, as well as improve limits on current neutrino oscillation parameters, by measuring oscillations of muon neutrinos and muon anti-neutrinos produced in the NuMI beam at Fermilab. The muon neutrino disappearance analysis specifically focuses on the measurements of $\Delta m_{32}^2$ and...

The Mu2e experiment will conduct a search for charged lepton flavor violation through observation of a neutrino-less muon-to-electron conversion. In order to reduce backgrounds from cosmic ray muons, a cosmic ray veto consisting of counters made from scintillating plastic will be read out by wavelength-shifting fibers. The cosmic ray veto must have an overall detection efficiency of 99.99%. In...

The NEXT collaboration is developing a sequence of high pressure xenon gas time projection chambers with the aim of creating a ton-scale, very low background neutrinoless double beta decay search. While most aspects of this technology are easily scalable, some detector elements require R&D in order to be realized on a large scale. This poster will describe a new, large-scale test facility...

The cosmic microwave background (CMB) is a rich source of information about the cosmos. Over the past ten years, gains in experimental sensitivity have enabled ground-based instruments to begin the search for B-mode polarization in the CMB as a test of the inflationary paradigm. However, the atmosphere is not fully transparent in the 35-270GHz region targeted by these observations. ...
