ABOUT THESES
The theses collection aims to cover as well as possible all theses in particle physics and its related fields.
The collection starts with the thesis of Feynman, defended in 1942, and covers now alltogether more than 3000 theses. Most of the documents are held as hard copies, theses from later years are available electronically. (Note also that many theses are not physically held by the CERN Library.)

Direct photon production at low transverse momentum in proton-proton collisions at $\sqrt{s}$ = 13 TeV / Murakami, Hikari
Direct photons are unique probes to study quark-gluon plasma (QGP) created in ultra-relativistic heavy-ion collisions, as they are emitted from the whole stages of the space-time evolution with negligible final state interaction [...]
