Phase field theory modeling of CH4/CO2 gas hydrates in gravity fields
(Peer reviewed; Journal article, 2011)Natural gas hydrates in reservoirs are thermodynamically unstable due to the interactions with surrounding fluids (aqueous, gas) and mineral surfaces. Depending on the local flow hydrate will dissociate as well as reform. ... -
Phase transitions in non-equilibrium dynamical systems
(Doctoral thesis, 2010-12-09)This work is a summary of three papers (references [5, 14, 24]), which deal with modelling the hadronization and freeze-out in heavy ion collisions. There is evidence that this is a non-equilibrium process, and therefore ... -
\(\phi\) meson production in Pb-Pb collisions at \(\sqrt s_{NN}\)=5.02 TeV with ALICE at the LHC
(Peer reviewed; Journal article, 2017-11)Strangeness production is a key tool to understand the properties of the medium formed in heavy-ion collisions: an enhanced production of strange particles was early proposed as one of the signatures of the Quark-Gluon ... -
\(\phi\)-meson production at forward rapidity in p-Pb collisions at \(\sqrt{s_{\rm NN}}\) = 5.02 TeV and in pp collisions at \(\sqrt{s}\) = 2.76 TeV
(Peer reviewed; Journal article, 2017-03)The first measurement of \(\phi\).meson production in p-Pb collisions at a nucleon-nucleon centre-of-mass energy \(\sqrt{s_{\rm NN}}\) = 5.02 TeV has been performed with the ALICE apparatus at the LHC. \(\phi\) mesons have ... -
Phonon-Mediated Quasiparticle Lifetime Renormalizations in Few-Layer Hexagonal Boron Nitride
(Journal article; Peer reviewed, 2023)Understanding the collective behavior of the quasiparticles in solid-state systems underpins the field of non-volatile electronics, including the opportunity to control many-body effects for well-desired physical phenomena ... -
Photon, neutrino and charged particle spectra from R-violating gravitino decays
(Peer reviewed; Journal article, 2010-03-22)We study photonic, neutrino and charged particle signatures from slow decays of gravitino dark matter in supersymmetric theories where R-parity is explicitly broken by trilinear operators. Photons and (anti-)fermions from ... -
Photoproduction of heavy vector mesons in ultra-peripheral Pb–Pb collisions
(Peer reviewed; Journal article, 2017-11)Ultra-peripheral Pb-Pb collisions, in which the two nuclei pass close to each other, but at an impact parameter greater than the sum of their radii, provide information about the initial state of nuclei. In particular, ... -
Photoproduction of ρ0 and Two–photon Production of Lepton Pairs in Ultra–peripheral Pb–Pb Collisions at the CERN LHC
(Doctoral thesis, 2014-06-10)This thesis is based on the analysis of ultra–peripheral collisions collected by the ALICE Collaboration at the CERN LHC. ALICE is a general purpose detector designed to study heavy-ion collisions at ultra–relativistic ... -
Photothermal convection of a magnetic nanofluid in a direct absorption solar collector
(Journal article; Peer reviewed, 2022)Nanofluid-based direct absorption of solar heat results in thermal efficiencies superior to conventional solar thermal technology. In addition, convection of nanofluid can be sustained pump-free in the collector. In this ... -
Photothermal conversion of biodegradable fluids and carbon black nanofluids
(Journal article; Peer reviewed, 2022)The paper is devoted to the topic of direct absorption solar collectors (DASCs). Various kinds of fluids can be used as heat transfer fluid in DASCs, and the main focus of our paper is on comparing nanofluids (water with ... -

\(\pi^0\) and \(\eta\) meson production in proton-proton collisions at \(\sqrt{s}=8\) TeV
(Peer reviewed; Journal article, 2018-03)An invariant differential cross section measurement of inclusive \(\pi^{0}\) and \(\eta\) meson production at mid-rapidity in pp collisions at \(\sqrt{s}=8\) TeV was carried out by the ALICE experiment at the LHC. The ... -
Pion, Kaon, and Proton Production in Central Pb--Pb Collisions at \(\sqrt{s_{NN}}\) = 2.76 TeV
(Peer reviewed; Journal article, 2012-12)In this Letter we report the first results on \(\pi^\pm\), K\)^\pm\), p and pbar production at mid-rapidity (|y|<0.5) in central Pb-Pb collisions at \(\sqrt{s_{NN}}\) = 2.76 TeV, measured by the ALICE experiment at the ... -
Pion-kaon femtoscopy in Pb–Pb collisions at √sNN=2.76TeV measured with ALICE
(Peer reviewed; Journal article, 2019)Femtoscopic correlations between charged pions and kaons for different charge combinations are measured in Pb−Pb collisions at √sNN = 2.76 TeV with ALICE at the LHC. The three-dimensional pion-kaon (π − K) correlation ... -
Pixel detector performance and study of CP invariance in H to tau tau decays with the ATLAS detector
(Doctoral thesis, 2018-04-27)Following its discovery by the ATLAS and CMS experiments in 2012, the Higgs boson has been studied in a multitude of decay modes. So far, its measured properties match very well with the predictions of the Standard Model ... -
Plan Selection in Proton Therapy of Locally Advanced Prostate Cancer with Simultaneous Treatment of Multiple Targets
