Event shapes are used in high-energy particle physics to describe the topology of particle collisions in experiments, such as those conducted at particle accelerators. Event shape variables are used to quantify the distribution of particles produced in a collision and provide information about the underlying dynamics of the interaction. These variables typically include measures of the angular distribution of particles in the collision, such as the thrust, sphericity, and jet broadening. These event shapes can be used to classify different types of collisions, such as quark-quark or quark-gluon interactions, and to study the properties of the particles produced in these interactions. Event shape studies are important for understanding the fundamental interactions of elementary particles and for testing the predictions of theoretical models, such as Quantum Chromodynamics (QCD). They are also used in experimental analyses to select events with specific characteristics and to search for new particles or interactions that deviate from the standard model of particle physics.
