"Accelerating Discovery in High Energy Physics using AI"
The past decade was marked by an exponential increase in the availability of experimental data in high energy physics, leading to unprecedented precision in the description of particle interactions. However, indirect evidence for new physics processes, such as the existence of dark matter, motivates the development of new methodologies to scrutinize the data in the search for new scientific discoveries. In this talk, I will introduce different applications of how artificial intelligence (AI) has been transformative in the way to analyse data from collider experiments. These include the development of fast simulation routines, high-dimensional deconvolution algorithms, and alternative ways to search new particle interactions. I will discuss future directions for each of these areas and potential synergies with other fields in the physical sciences.

Relativistic dilation explains dark matter. It's the phenomenon our high school teachers were talking about when they said "mass becomes infinite at the speed of light". This does not mean mass increases, it means mass becomes spread throughout spacetime relative to an outside observer. Time dilation is just one aspect of dilation, it's not just time that gets dilated. Even mass that exists at 75% light speed is partially dilated.
It occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers.
Our own galactic center is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. It's the "missing mass" needed to explain galaxy rotation curves.
Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 ultra diffuse galaxies including NGC 1052-DF2 and DF4 to have no dark matter.
Mass is a clingy thing thanks to gravity, it makes sense that dilated mass would exist as a halo around galaxies.
