38. Recent hot-spot model results

The Hot-spot model, based on color dipole approach, provides a description of the proton structure in the transverse plane by hot spots. Hot spots are localized regions of higher partonic densities, whose positions change event-by-event. The number of hot spots increases with decreasing Bjorken-x. Moreover, the effects of making the radius of the proton and radius of hot spots energy dependent...

39. Recent BK results

The structure of hadrons is a complex open question in modern physics. The inner working of quantum chromodynamics allows for a dynamical evolution of the structure and a fast growth of the densities of hadron constituents with respect to their fractional momentum. At some point, this unlimited growth needs to be curbed and saturation is expected to occur. The Balitsky-Kovchegov (BK) equation...

40. Fitting with correlated uncertainties

Jesus Guillermo Contreras

9/14/23, 2:40 PM

One of the main motivations of the meeting is to share the different techniques that one member of the team uses so that the rest of the team can profit from this knowledge. A case in point is the estimation of model parameters using data that has correlated uncertainties. A method based on Lagrange multipliers, used by the H1 and ALICE Collaboration, is presented. An example of its...

44. Introduction to decision trees

Dagmar Bendová (CTU FNSPE)

9/14/23, 3:00 PM

Prepare to delve into the fascinating intersection of particle physics and machine learning. Our mission is to demystify the intricate landscape of decision trees while maintaining a conversational and accessible tone. We'll navigate beyond theory, delving into the practical implications of decision trees. These powerful algorithms play a central role in deciphering complex datasets by...
