Title: Investigating the quark-gluon plasma in proton-proton collisions

Abstract: The quark-gluon plasma (QGP) is a phase of QCD matter that occurs at
temperatures of a few trillion Kelvin, wherein the degrees of freedom
are not colorless hadrons but deconfined quarks and gluons. The QGP
occurred naturally in the early universe a few microseconds after the
Big Bang, when the temperature of the universe was above the
deconfinement temperature. The QGP can be recreated in particle
colliders by colliding "heavy" nuclei, like lead or gold, at
relativistic energies. Until a few years ago, it was believed that the
QGP can only be recreated in such "heavy-ion" collisions. However,
measurements in proton-proton (pp) collisions showed the presence of
features that are strikingly similar to those observed in heavy-ion
collisions. This raises the possibility that a tiny droplet of the QGP
is produced even in pp collisions. However, these features can also be
qualitatively reproduced by theoretical models that attribute their
origin to semi-hard processes. In this talk I will present several
recent measurements that aim to establish whether or not the QGP is
produced in pp collisions.
