Probing new physics mechanisms in neutrinoless double-beta decay with SNO+
PhDIn this thesis, I present the theory of neutrinoless double-beta decay (0 2 ),
particularly the theory of exotic modes of 0 2 involving the emission of
one or two Majorons. Alongside this, I summarise the most recent results
in the experimental search for 0 2 , including limits on the rate of these
exotic processes. I describe the SNO+ experiment and it’s physics goals,
which include the search for 0 2 . As part of the SNO+ collaboration, I
have made a signi cant contribution towards the development of the data
quality software that is essential for ensuring SNO+ can achieve its physics
goals—including in 0 2 searches. I describe how I developed a software
package that performs the high-level data quality checks.
Continuing with the software theme, I then describe a python-based
limit-setting and tting software package called echidna. I have been a lead
developer of echidna as part of my PhD, so I describe the software in detail
and how it can be used to set limits on 0 2 signals. By reproducing the
sensitivity results of the KamLAND-Zen experiment, in four key Majoronemitting
0 2 modes, I verify the use of echidna as a limit-setting tool
for this type of search. Finally, I present the results of a comprehensive
sensitivity study, where I determine the potential sensitivity of SNO+ to the
same set of Majoron-emitting modes that KamLAND-Zen and other 0 2
experiments have already investigated
P1_1 Could Bruce Willis Save the World?
The film Armageddon (1998) puts forward the possibility of using a nuclear weapon buried deep within an Earth-bound asteroid to split the asteroid in two, each half clearing opposite sides of the Earth with only relatively minor damage. This article investigates the feasibility of such a plan and shows that even using the largest nuclear weapon made to date, the bomb comes over 9 orders of magnitude short of the yield required
P1_10 Delta-V Requirements of Spaceflight
The paper calculates the delta-V requirements to launch a spacecraft into Low Earth Orbit and execute Hohmann transfers to the International Space Station orbit and Geosynchronous Orbit. These were found to be 8.03 kms-1, 0.12 kms-1 and 3.94 kms-1, respectively. The paper also includes researched values for the delta-V requirements to travel to the Moon and Phobos. The paper aims to highlight the fact that delta-V requirements for manoeuvres beyond Low Earth Orbit are considerably lower than achieving Low Earth Orbit.Â
P1_3 Speed Limit
 To be able to go faster than anyone else is a dream held by many people, including the Vesco family, who set the current land speed record for a wheel-driven vehicle in their car The Turbinator. By considering the balance of drive force and drag force on an ideal track, this paper estimates the theoretical top speed of The Turbinator. Then by analysing the new power output of their modified engine, the possibility of exceeding 500 mph was explored
P1_6 Paper Planes - Long-Haul Flight
 This article analyses key factors in the design of a paper aeroplane and its flight dynamics that result in large flight times. The theoretical maximum height of the flight is found to be 33 m and the lift coefficient is estimated as 0.06 (s^2)/m. The key factors for extended flight are maximum wing area, high launch speed and minimum paper weight
P1_4 Could Bruce Willis Predict the End of the World?
This article is a follow-â€up to the paper Could Bruce Willis Save the World? where the feasibility of splitting an asteroid with a nuclear weapon is studied. In this article the possibility of spotting the asteroid with the Hubble Space Telescope upon a lucky image was researched. It was found the asteroid could have been spotted as far as away as 1.3210^14ð‘š
