Thermomechanical Properties Of Aluminium Heaters To Test The Compact Muon Solenoid Cooling System For Phase Two Upgrade, Sandra Jimena González, Timothy Matthew Jones

The Summer Undergraduate Research Fellowship (SURF) Symposium

The main objectives of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider are precision studies of the Standard Model of Particle Physics and the discovery of physics beyond it. To meet that, it is essential for the CMS detector to function at the highest efficiency for detecting subatomic particles within various technical constraints. In particular, the readout chips of the Pixel Tracker sub-detector produce significant heat and must be kept at -10 °C to ensure optimal performance and reduce cumulative damage in the high radiation environment. Thus, it is necessary to design a cooling system to extract …

In process of analyzing large amounts of quantitative data, it can be quite time consuming and challenging to uncover populations of interest contained amongst the background data. Therefore, the ability to partially automate the process while gaining additional insight into the interdependencies of key parameters via machine learning seems quite appealing. As of now, the primary means of reviewing the data is by manually plotting data in different parameter spaces to recognize key features, which is slow and error prone. In this experiment, many well-known machine learning algorithms were applied to a dataset to attempt to semi-automatically identify known populations, …

Searching For The Origins Of Matter, Joshua L. Barrow

Andrews Research Conference

The big bang and inflation are experimentally confirmed by multitudes of astronomical observations, yet theoretical tension still exists upon a very important question: why is there something rather than nothing? In other words, why are there unequal amounts of matter and antimatter? Why did a supposedly initially symmetric state not annihilate perfectly?

The breaking of this symmetry has allowed for all of material existence--also known as baryogenesis, the prevalence of matter over antimatter--and yields the theoretical possibility of direct detection by observation of baryon number violating mechanisms, which have previously never been observed.

One such plausible mechanism can be found …
