    Probing new physics mechanisms in neutrinoless double-beta decay with SNO+

    Get PDF
    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

    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_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_10 Delta-V Requirements of Spaceflight

    Get PDF
    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_6 Paper Planes - Long-Haul Flight

    Get PDF
     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?

    Get PDF
    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
