Welcome to the MMTE workshop and event logistics
The aim of this talk is to set the stage for the neutrino tomography workshop and to provide basic information about the properties of atmospheric neutrinos. I will present a pedagogical overview on atmospheric neutrinos, their history, and briefly review their current use in the study of neutrino oscillation.
Earthquakes, ocean waves, and human activity produce seismic waves that travel through the Earth, carrying with them information about variations in elastic properties and density. Since pioneering efforts in the late 1970s, global seismic tomography has revealed structures in our planet's deep interior at increasingly greater detail. Here, I present recent progress in determining Earth's...
The world largest neutrino observatory IceCube, located at the South Pole, is collecting high-energy neutrino events for over 10 years, and has observed a diffuse cosmic neutrino flux since 2013. While the main aim is searching for extra-terrestrial neutrinos, the collected data contains a large sample of atmospheric neutrino interactions as background events. Using our understanding of the...
Hydrogen is a strongly siderophile (iron-loving) element under typical conditions of Earth’s core formation (40–50 GPa, ~3500 K); its metal/silicate partition coefficient D(H) (metal/silicate) = ~50 by weight (Tagawa et al., 2021 Nat. Commun.). Considering the amount of H2O in the mantle and oceans, such high D(H) (metal/silicate) suggests 0.3–0.6 wt% H in the core, which accounts for...
I would give a brief review on the topic concerning the core-mantle co-evolution in terms of thermal and chemical evolution of Earth’s core constrained from the mantle dynamics of Earth. In this talk, several controversial aspects in current understandings of thermal and chemical evolution of the Earth’s core will be introduced: 1. The age of inner core (greatly uncertain in between ~1 Ga to 3...
We study in details the Earth matter effects on the boron neutrinos
from the Sun using recently developed 3D models of the Earth.
The models have a number of new features of the density profiles,
in particular, a substantial deviation from spherical symmetry.
In this connection, we further elaborate on relevant aspects
of oscillations ($\epsilon^2$ corrections, adiabaticity violation,...
In the last decade IceCube has opened a new window on the Universe using neutrinos as astronomical messengers. The instrument detects more than 100,000 neutrinos per year in the GeV to 10,000 TeV energy range. IceCube and similar detectors now under construction or at the concept stage, will perform neutrino physics with high statistics samples of atmospheric neutrinos and with the beam of...
The Earth's core may be divided into two main regions: a solid inner core; and a liquid outer core. At the base of the outer core is a seismologically anomalous layer, likely denser than the liquid above. There may also be a low-density layer at the top of the outer core. The solid inner core is divided into two regions: a seismically anisotropic inner zone, and an isotropic layer on top....
Using PREM as a reference model for the
Earth density distribution we present results on
the sensitivity of ORCA detector to deviations of the Earth
i) outer core (OC) density, ii) inner core (IC) density,
iii) total core density, and iv) mantle density,
from their respective PREM densities.
The results are obtained in EPJ C82 (2022) 461
by studying the effects of the Earth matter
on...
Seismic imaging of the structure of Earth’s inner core remains a challenging topic. The inner core occupies < 1% of Earth’s volume and the few seismic waves that do sample it can be significantly influenced by heterogeneities in the overlying crust and mantle. Furthermore, the seismic sources and receivers used in imaging the inner core are located at or near (< 700 km depth) Earth’s surface...
The core-mantle boundary (CMB) region is both a compositional and thermal boundary layer with the largest density contrast anywhere in the planet. As a result, the structures found within the lowermost mantle are as complex as those found on the Earth’s surface. In this presentation we review the major features that have been identified from seismological studies. We review features at (1)...
In Earth’s deepest mantle, there are two huge structures with anomalously lower seismic velocities, and perhaps different compositions, than their surroundings. One such structure is found beneath Africa and the other is beneath the Pacific Ocean. They are often called “Large Low Velocity Provinces”. These structures are footprints of Earth’s long-term evolution. By examining their morphology...
The neutrino oscillation probability depends on the electron density of the media and next generation neutrino detector will have the capability to resolve the earth's electron density distribution with some accuracy.
If we combine the earth's matter density distribution and electron density distribution, then we can obtain the average chemical compositional distribution as Z/A ratio. Also...
The Iron Calorimeter (ICAL) detector at the proposed India-based Neutrino Observatory (INO) aims to detect atmospheric neutrinos and antineutrinos separately in the multi-GeV range of energies and over a wide range of baselines. By utilizing its charge identification capability, ICAL can efficiently distinguish $\mu^-$ and $\mu^+$ events. Atmospheric neutrinos passing long distances through...
Earth's core plays a fundamental role in the evolution and habitability of our planet. Understanding its composition is key to interpreting the history of Earth's accretion. The density model suggests that the Earth's core is predominantly composed of iron (or iron-nickel alloy) with several percent of light elements, such as Si, S, C, O, and H, but their abundances in the Earth's core remain...
Neutrinos change flavor as they travel, and this probability depends on the density of electrons in the material they are traveling through. So, we can use neutrinos produced in the atmosphere by cosmic rays to tell us about the density of electrons in the Earth. In this talk, I will present our simulations of this phenomenon that we did in determining the sensitivity of the Deep Underground...
This talk will show how the Earth's density profile can be measured in the DUNE experiment using atmospheric neutrinos. After crossing the Earth, neutrinos give us access to a rich oscillation phenomenology that strongly depends on the matter potential sourced by the Earth. By performing a detailed simulation of the event reconstruction capabilities of liquid argon time projection chambers,...
The workshop will focus on negotiation and communication skills useful to physics researchers as they navigate their careers, including how to:
- Negotiate a position in academia, industry, or at a national lab
- Interact positively on teams and with a mentor or advisor
- Think tactically
- Enhance personal presence
- Develop alliances
- Achieve professional goals
