Strangeness production in proton-proton and proton-nucleus collisions [PDF]

open access: yesPramana, 2005
In these lectures we discuss the investigation of the strange meson production in proton-proton ($pp$) and in proton-nucleus ($pA$) reactions within an effective Lagrangian model. The kaon production proceeds mainly via the excitations of $N^*$(1650), $N^

Precision luminosity measurement in proton-proton collisions at s = 13 TeV in 2015 and 2016 at CMS. [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The measurement of the luminosity recorded by the CMS detector installed at LHC interaction point 5, using proton-proton collisions at s = 13 TeV in 2015 and 2016, is reported.

The strangest proton? [PDF]

open access: yesThe European Physical Journal C, 2020
AbstractWe present an improved determination of the strange quark and antiquark parton distribution functions of the proton by means of a global QCD analysis that takes into account a comprehensive set of strangeness-sensitive measurements: charm-tagged cross sections for fixed-target neutrino–nucleus deep-inelastic scattering, and cross sections for ...

Performance of the CMS Level-1 trigger in proton-proton collisions at √s = 13 TeV [PDF]

open access: yesJournal of Instrumentation, 2020
At the start of Run 2 in 2015, the LHC delivered proton-proton collisions at a center-of-mass energy of 13 TeV. During Run~2 (years 2015--2018) the LHC eventually reached a luminosity of 2.1 $\times$ 10$^{34}$ cm$^{-2}$ s$^{-1}$, almost three times that ...

Amide proton transfer imaging-arterial spin labeling mismatch: a new imaging biomarker for pilocytic astrocytoma

open access: yesScientific Reports, 2023
We describe the potential utility of Amide Proton Transfer weighted (APTw) Magnetic Resonance Imaging and arterial spin labeling (ASL) in characterizing pilocytic astrocytoma (PA), a type of brain tumor that can be challenging to accurately diagnose and ...

Leptons in the proton [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract As is the case for all light coloured Standard Model particles, also photons and charged leptons appear as constituents in ultrarelativistic hadron beams, and admit a parton density function (PDF). It has been shown recently that the photon PDF can be given in terms of the structure functions and form factors for electron ...

Proton-proton interactions and onset of deconfinement [PDF]

open access: yesPhysical Review C, 2020
The experiment of the NA61/SHINE Collaboration at the CERN SPS is performing a unique study of the phase diagram of strongly interacting matter by varying collision energy and nuclear mass number of colliding nuclei. In central Pb+Pb collisions, the experiment of the NA49 Collaboration found structures in the energy dependence of several observables in
