5 Minute Talks

Research developments in recent years have given strong evidence that
one-loop Feynman diagrams admit a coaction, a conjectural statement
regarding the algebraic and analytic structure of the corresponding
Feynman integrals. In this talk, I will explain how one defines a coaction and show how it may apply to Feynman Diagrams.
The WKB approximation describes the decay of metastable states in quantum mechanics but its extension to multidimensional field theory is not trivial. I will give a short overview of the original Euclidean approach developed by Coleman et al. in the 1980's as well as more recent approaches and comment on the different predictions between the two.
Putting chiral fermions on a lattice has been a long standing problem due to the doubling problem. I'll briefly introduce this and talk about potential ways of solving it.
We investigate the Lagrangian formulation of the double-copy correspondence between gauge theories and gravity, up to the cubic order. Building on the definition of the double-copy field as a convolution of two vectors, we obtain free gravitational Lagrangians as products of two Yang-Mills Lagrangians, in a form amenable to be easily extended to the massive case. We discuss the origin of these...
Diagnosing cancer may be performed from biofluids, utilizing Raman spectrophotometry, multiple machine learning techniques and their applications in particle detectors. Nonetheless, algorithms which would allow for accurate classification model in this scenario would require incorporating the information from patient's medical record. Them main challenge of this project is to design an...
I will briefly introduce my research work on higher form symmetries and it's connection to geometrically engineered field theories.
This talk is an overview of infrared divergences required in precision QCD calculations. The cancellation of these divergences is necessary by KLN theorem and must be verified when predicting observables. Improvements on methods in this type of work is necessary to extend predictions to $\text{N}^3\text{LO}$ in $\alpha_\text{s}$, to make comparisons with future precise collider experiments....
Yang-Mills theories based on the Symplectic groups (denoted by $Sp(2N)$) have the potential to describe a composite Higgs particle. To gain a better understanding of such theories, it is important to understand the dynamics of the pure Yang-Mills sector as well as in the presence of fermions. A detailed study of the glueball spectrum has been carried out for $N=1,2,3$ and 4 along with an...
Dessins d'enfants will be introduced, discussing their link to Calabi-Yau manifolds in string theory and their importance in Galois theory. Following this we will briefly discuss work performed to classify a database of dessins d'enfants according to their Galois orbit size using machine-learning.

Quantities representing measurables in physics should not depend on the method of calculating them in the underlying QFT. However, in perturbative QCD, computations must be truncated to a finite order meaning they are only approximations of the true quantity resulting in dependence on the renormalization scheme chosen. We investigate this dependence for the Bjorken sum rule and Adler D...
