14:00 - 14:35
We investigate mergers of neutron stars consisting of two non-interacting fluids minimally coupled to the gravitational field using the numerical relativity code BAM. The first fluid represents baryonic matter, whereas the second fluid models dark matter, which we describe using the equation of state of a degenerate Fermi gas. We consider two different scenarios for the distribution of the dark matter. In the first scenario the dark matter is confined to the core of the star, whereas in the second scenario the dark matter extends beyond the surface of the baryonic matter forming a halo around the baryonic star. We show how the dark matter impacts the binary dynamics and merger waveforms.

14:00 NLO QCD Corrections to (pseudo)Scalar and Chiral to quark pair Vertices using IReg - Ricardo Jorge Carvalho Rosado
NLO QCD Corrections to (pseudo)Scalar and Chiral to quark pair Vertices using IReg
- Ricardo Jorge Carvalho Rosado
14:00 - 14:40
The improvement of experimental results as led to the need of equally precise, and practical, theoretical approaches to the Standard Model. The Implicit Regularisation (IReg) framework sets itself apart of more conventional dimensional schemes as it works purely in the physical 4 dimensions, which eases some problems of the aforementioned, like the need for evanescent fields. In this work we test the implementation of IReg onto the decay rate of the Z0 boson as well as a scalar and pseudo-scalar bosons into a quark anti-quark pair at NLO in QCD.

Symbolic Regression (SR): an overview
- Felipe Demigio
14:00 - 14:40
Symbolic Regression (SR) is a type of regression analysis used to find the model which can best fit a dataset according to a specified condition by conducting a search on the space of mathematical expressions. This talk aims to give an introduction to this topic, to succinctly present a few popular and particularly Physics-oriented search algorithms, and to showcase examples of SR’s application in research
