Flow in pPb collisions at 5 TeV?
K. Werner, B. Guiot, Iu. Karpenko +1
There is little doubt that hydrodynamic flow has been observed in heavy ion collisions at the LHC and RHIC, mainly based on results on azimuthal anisotropies, but also on particle…
Multinucleon transfer reactions in closed-shell nuclei
S. Szilner, C. A. Ur, L. Corradi +29
Multinucleon transfer reactions in 40Ca+96Zr and 90Zr+208Pb have been measured at energies close to the Coulomb barrier in a high resolution gamma-particle coincidence experiment.…
Spacetime development of in-medium hadronization: Scenario for leading hadrons
B. Guiot, B. Z. Kopeliovich
We present a perturbative QCD based model for vacuum and in-medium hadronization. The effects of induced energy loss and nuclear absorption have been included. The main objective i…
production at NLO with a scale-dependent color-evaporation model
B. Guiot, A. Radic, I. Schmidt +1
Nearly ten years ago, Kang, Ma, Qiu, and Sterman derived an evolution equation for a pair fragmenting into a quarkonium. In this study we explore the consequence of this…
Dynamical effects in multifragmentation at intermediate energies
J. Colin, D. Cussol, J. Normand +34
The fragmentation of the quasi-projectile is studied with the INDRA multidetector for different colliding systems and incident energies in the Fermi energy range. Different experim…
Heavy-hadron production based on -factorization with scale-dependent fragmentation functions
F. E. Barattini, C. O. Dib, B. Guiot
We present a comprehensive study of heavy-hadron production, including and mesons, heavy baryons, and the meson. Our calculations are based on the -factorization…
D and B-meson production using kt-factorization calculations in a variable-flavor-number scheme
B. Guiot, A. van Hameren
Within the framework of -factorization, we compute the differential cross section for the production of and mesons, using a general-mass variable-flavor-number scheme.…
Evidence for flow in pPb collisions at 5 TeV from v2 mass splitting
K. Werner, M. Bleicher, B. Guiot +2
We show that a fluid dynamical scenario describes quantitatively the observed mass splitting of the elliptical flow coefficients v2 for pions, kaons, and protons. This provides a s…
Dynamics and thermodynamics of phase transition in hot nuclei
M. F. Rivet, N. Bellaize, B. Borderie +8
The dynamics and thermodynamics of phase transition in hot nuclei are studied through experimental results on multifragmentation of heavy systems (A>200) formed in central heavy io…
Examination of -factorization in a Yukawa theory
B. Guiot, A. van Hameren
We discuss the upper limit, , of the transverse-momentum integration performed in the -factorization formula. Based on explicit calculations in the Yukawa theo…
Analysing radial flow features in p-Pb and p-p collisions at several TeV by studying identified particle production in EPOS3
K. Werner, B. Guiot, Iu. Karpenko +1
Experimental transverse momentum spectra of identified particles in p-Pb collisions at 5.02 TeV show many similarities to the corresponding Pb-Pb results, the latter ones usually b…
Liquid-gas phase transition in hot nuclei studied with INDRA
B. Borderie, R. Bougault, P. Desesquelles +11
Thanks to the high detection quality of the INDRA array, signatures related to the dynamics (spinodal decomposition) and thermodynamics (negative microcanonical heat capacity) of a…
Liquid-gas phase transition in hot nuclei: correlation between dynamical and thermodynamical signals
M. F. Rivet, B. Borderie, R. Bougault +8
The dynamics and thermodynamics of phase transition in hot nuclei are studied through experimental results on multifragmentation of heavy systems (A200) formed in central heav…

Influence of final-state radiation on heavy-flavour observables in pp collisions
L. Vermunt, J. Aichelin, P. B. Gossiaux +5
The influence of final-state radiation (FSR) of heavy quarks on observables in high-energy proton-proton collisions is studied. The transverse momentum correlation of D and Dbar me…
Charm production in high multiplicity pp events

A unified description of the reaction dynamics from pp to pA to AA collisions
K. Werner, B. Guiot, I. Karpenko +1
There is little doubt that in heavy ion collisions at the LHC and RHIC, we observe a hydrodynamically expanding system, providing strong evidence for the formation of a Quark Gluon…
Graviballs and Dark Matter
B. Guiot, A. Borquez, A. Deur +1
We investigate the possible existence of graviballs, a system of bound gravitons, and show that two gravitons can be bound together by their gravitational interaction. This idea co…
