The CMS collaboration at CERN has selected one of the analyses on which IFCA's Particle Physics team is working to highlight it for its special relevance. Pablo Martínez Ruiz del Árbol is one of the founders of this analysis.

The Standard Model of Particle Physics is the theory that physicists use to describe elementary particles’ fundamental interactions. The Standard Model was developed over many decades. It has been able to predict experimental observations with remarkable accuracy, including the existence of the Higgs boson, discovered at the Large Hadron Collider (LHC) back in 2012.
What the Standard Model can not explain, such as the existence of dark matter and the fact that the particles have different masses and different strengths, is what physicists explain with physics beyond the Standard Model. There are many physics theories beyond the Standard Model; one of those carries the name of Supersymmetry (SUSY).
SUSY predicts that for each elementary particle of the Standard Model, a supersymmetric partner particle exists, only differing from the former because of its spin and mass. For SUSY to correctly describe the experimental observations of the last few decades, it actually must consist of a spontaneously broken symmetry, thus allowing partner particles to differ in mass too.
In a new paper, the CMS collaboration searches for supersymmetric versions of particles we already know and understand, such as the electron and muon, called superleptons.
