Convergence of the correlation function within the hyperspherical adiabatic basis
E. Garrido, A. Kievsky, R. Del Grande +3
The computation of the three-particle correlation function involving three hadrons started just recently after the first publications of ALICE measurements. Key elements to be cons…
The and correlation functions
E. Garrido, A. Kievsky, M. Gattobigio +5
In this work we present the study of and scattering processes using femtoscopic correlation functions. This observable has been recently used to access the low-energy in…
The correlation function with a screened Coulomb potential
A. Kievsky, E. Garrido, M. Viviani +1
The correlation function is a useful tool to study the interaction between hadrons. The theoretical description of this observable requires the knowledge of the scattering wave fun…
The and correlation functions
A. Kievsky, E. Garrido, M. Viviani +3
Scattering experiments with three free nucleons in the ingoing channel are extremely challenging in terrestrial laboratories. Recently, the ALICE Collaboration has successfully mea…
Breakup of three particles within the adiabatic expansion method
E. Garrido, A. Kievsky, M. Viviani
General expressions for the breakup cross sections in the lab frame for reactions are given in terms of the hyperspherical adiabatic basis. The three-body wave function is ex…
Recombination rates from potential models close to the unitary limit
E. Garrido, M. Gattobigio, A. Kievsky
We investigate universal behavior in the recombination rate of three bosons close to threshold. Using the He-He system as a reference, we solve the three-body Schrödinger equation…
Integral relations and the adiabatic expansion method for 1+2 reactions above the breakup threshold: Helium trimers with soft-core potentials
E. Garrido, C. Romero-Redondo, A. Kievsky +1
The integral relations formalism introduced in \cite{bar09,rom11}, and designed to describe 1+ reactions, is extended here to collision energies above the threshold for the targ…
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…
