Solid State Detectors and Tracking for Snowmass
A. Affolder, A. Apresyan, S. Worm +132
Tracking detectors are of vital importance for collider-based high energy physics (HEP) experiments. The primary purpose of tracking detectors is the precise reconstruction of char…
General integral relations for the description of scattering states using the hyperspherical adiabatic basis
C. Romero-Redondo, E. Garrido, P. Barletta +2
In this work we investigate 1+2 reactions within the framework of the hyperspherical adiabatic expansion method. To this aim two integral relations, derived from the Kohn variation…
The helium trimer with soft-core potentials
A. Kievsky, E. Garrido, C. Romero-Redondo +1
The helium trimer is studied using two- and three-body soft-core potentials. Realistic helium-helium potentials present an extremely strong short-range repulsion and support a sing…
Variational description of continuum states in terms of integral relations
A. Kievsky, M. Viviani, P. Barletta +2
Two integral relations derived from the Kohn Variational Principle (KVP) are used for describing scattering states. In usual applications the KVP requires the explicit form of the…
Integral relations for three-body continuum states with the adiabatic expansion
P. Barletta, C. Romero-Redondo, A. Kievsky +2
Application of the Hyperspherical Adiabatic expansion to describe three-body scattering states suffers the problem of a very slow convergence. Contrary to what happens for bound st…
The harmonic hyperspherical basis for identical particles without permutational symmetry
M. Gattobigio, A. Kievsky, M. Viviani +1
The hyperspherical harmonic basis is used to describe bound states in an --body system. The approach presented here is based on the representation of the potential energy in ter…
Three-Nucleon Continuum by means of the Hyperspherical Adiabatic Method
P. Barletta, A. Kievsky
This paper investigates the possible use of the Hyperspherical Adiabatic basis in the description of scattering states of a three-body system. In particular, we analyze a 1+2 colli…
Creating ultracold molecules by collisions with ultracold rare gas atoms in an optical trap
P. Barletta, J. Tennyson, P. F. Barker
We study collisions of para-H with five rare gas atomic species (He, Ne, Ar, Kr and Xe) over the range from 1 K to 1 K and evaluate the feasibility of sympathetic cooling H…
Comparative study of Rare Gas-H triatomic complexes
Paolo Barletta
This paper presents a comparative analysis of complexes made of one Rare Gas (Rg) atom and molecular hydrogen, for all five stable Rg atoms. In particular, the vibrational band ori…
Variational Estimates using a Discrete Variable Representation
M. Lombardi, P. Barletta, A. Kievsky
The advantage of using a Discrete Variable Representation (DVR) is that the Hamiltonian of two interacting particles can be constructed in a very simple form. However the DVR Hamil…
Microscopic study of the He2-SF6 trimers
P. Barletta, A. Fabrocini, A. Kievsky +2
The He2-SF6 trimers, in their different He isotopic combinations, are studied both in the framework of the correlated Jastrow approach and of the Correlated Hyperspherical Harmonic…
Variational description of the Helium trimer using correlated hyperspherycal harmonic basis functions
Paolo Barletta, Alejandro Kievsky
A variational wave function constructed with correlated Hyperspherical Harmonic functions is used to describe the Helium trimer. This system is known to have a deep bound state. In…
