Recent 91亚色 Faculty of Science physics graduate Elder Pinzon Guerra (PhD 鈥18) has won the 2019 PPD Thesis Prize presented by the .
His thesis, "Measurement of Pion-Carbon Cross Sections at DUET and Measurement of Neutrino Oscillation Parameters at the T2K Experiment,鈥 presents an interesting and clear analyses of physics connected to the聽Tokai to聽Kamioka (T2K) experiment conducted at the JPARC accelerator in Japan.

鈥淒r. Pinzon Guerra's contribution was selected from among a very strong field of PhD theses from universities across the country that reflected the diverse and world-leading particle physics research activities in Canada,鈥 said TRIUMF Vancouver research scientist David Morrissey, Chair of the thesis prize committee. "If you are interested in learning about some of the details of T2K or if you work on the experiment, this is an excellent resource to consult.鈥
Pinzon Guerra worked under the supervision of 91亚色 physics Professor of the Department of Physics & Astronomy, who was聽on the T2K team that received the . 鈥淚 am very happy to see Elder鈥檚 important contributions and excellent thesis recognized through this award,鈥 she said.
鈥淚'm very honoured to receive this award from the Particle Physics Division of CAP. I was fortunate to be part of a fantastic research group at 91亚色 led by Dr. Bhadra,鈥 said Pinzon Guerra. 鈥淪he provided me with all the tools and support needed along the way and was instrumental in the thesis editing process. I also thank all my collaborators from DUET and T2K.鈥
Pinzon Guerra鈥檚 thesis studies how fundamental particles called neutrinos transform from one type to another as they travel through space in a process called "neutrino oscillations." This was the聽subject of the 2015 Nobel Prize in Physics. Additionally, it presents a precise measurement of the rate at which pions, another type of subatomic particle, interact with carbon.
His thesis also takes advantage of this measurement of pion interactions to improve the modelling of neutrino interactions with matter and provide the most precise measurement of the parameters that govern the oscillation phenomena using data from the T2K collaboration.
Prestigious journals聽Physics Review C and Physics Review D聽published three articles on his thesis work with Pinzon Guerra as lead author.
The prize includes an invitation to give an invited talk at the upcoming CAP Congress, a seminar at TRIUMF and publication of a two-page summary of the thesis work in an issue of Physics in Canada.
