Hot and cold nuclear matter effects in p–Pb collisions at the LHC

open access: yesEPJ Web of Conferences, 2015
The pA system is typically regarded in heavy ion collisions as a “cold” nuclear matter environment and thought to isolate and identify initial state effects due to the presence of multiple nucleons in the incoming nucleus.

Direct photon production in pp, p-Pb and Pb-Pb collisions: results from ALICE [PDF]

open access: yesEPJ Web of Conferences, 2019
Direct photon measurements provide a tool for testing QCD predictions in pp collisions and valuable information about properties of the quarkgluon matter created in nucleus-nucleus collisions.

Cold collisions catalyse conformational conversion [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2007
We have determined the abundance of two different conformational structures of the mixed benzene dimer (C(6)H(6))(C(6)D(6)) in a molecular beam, with various carrier gases. These two T-shaped conformers have a subtle zero-point energy difference of only a few cm(-1), and a transition state barrier of about 64 cm(-1).

A compact design for a magnetic synchrotron to store beams of hydrogen atoms

open access: yesNew Journal of Physics, 2015
We present a design for an atomic synchrotron consisting of 40 hybrid magnetic hexapole lenses arranged in a circle. We show that for realistic parameters, hydrogen atoms with a velocity up to 600 m s ^−1 can be stored in a 1 m diameter ring, which ...

Direct observation of swap cooling in atom–ion collisions

open access: yesNew Journal of Physics, 2021
Collisions with cold particles can dissipate a hot particle’s energy and therefore can be exploited as a cooling mechanism. Kinetics teach us that cooling a particle down by several orders of magnitude typically takes many elastic collisions as each one ...

Cold collisions of complex polyatomic molecules [PDF]

open access: yesThe Journal of Chemical Physics, 2012
We introduce a method for classical trajectory calculations to simulate collisions between atoms and large rigid asymmetric-top molecules. We investigate the formation of molecule-helium complexes in buffer-gas cooling experiments at a temperature of 6.5 K for molecules as large as naphthalene.

Reactive collisions in confined geometries

open access: yesNew Journal of Physics, 2015
We consider low energy threshold reactive collisions of particles interacting via a van der Waals potential at long range in the presence of external confinement and give analytic formulas for the confinement modified scattering in such circumstances ...

Energy-energy correlators in p-Pb collisions at ALICE [PDF]

open access: yesEPJ Web of Conferences
Jet substructure is a powerful tool for testing QCD in elementary particle collisions. The two-point energy-energy correlator (EEC), defined as the energy-weighted cross section of particle pairs inside jets, is a novel jet-substructure observable ...

Jet energy-energy correlator in cold QCD matter [PDF]

open access: yesEPJ Web of Conferences
We present a study of medium-induced modifications to the energy-energy correlator (EEC) for jets in cold nuclear matter. For electron-nucleus collisions, at leading order in the QCD coupling and in the jet-medium interaction, we derive an analytic ...
