On the relativistic Lagrange-Laplace secular dynamics for extrasolar systems
M. Sansottera, L. Grassi, A. Giorgilli
We study the secular dynamics of extrasolar planetary systems by extending the Lagrange-Laplace theory to high order and by including the relativistic effects. We investigate the l…
The Two Loop Crossed Ladder Vertex Diagram with Two Massive Exchanges
U. Aglietti, R. Bonciani, L. Grassi +1
We compute the (three) master integrals for the crossed ladder diagram with two exchanged quanta of equal mass. The differential equations obeyed by the master integrals are used t…
Dipolar degrees of freedom and Isospin equilibration processes in Heavy Ion collisions
M. Papa, I. Berceanu, L. Acosta +29
Background: In heavy ion collision at the Fermi energies Isospin equilibration processes occur- ring when nuclei with different charge/mass asymmetries interacts have been investig…
Isospin Dependence of Incomplete Fusion Reactions at 25 Mev/a
F. Amorini, G. Cardella, G. Giuliani +29
40Ca+40,48Ca,46Ti reactions at 25 MeV/A have been studied using the 4p CHIMERA detector. An isospin effect on the competition between incomplete fusion and dissipative binary react…
Identity and divergence of protein domain architectures after the Yeast Whole Genome Duplication event
D. Fusco, L. Grassi, A. L. Sellerio +4
Analyzing the properties of duplicate genes during evolution is useful to understand the development of new cell functions. The yeast S. cerevisiae is a useful testing ground for t…
Pulse shape discrimination for GRIT: beam test of a new integrated charge and current preamplifier coupled with high granularity Silicon detectors
J. -J. Dormard, M. Assié, L. Grassi +13
The GRIT (Granularity, Resolution, Identification, Transparency) Silicon array is intended to measure direct reactions. Its design is based on several layers (three layers in the f…
The ASY-EOS experiment at GSI: investigating the symmetry energy at supra-saturation densities
P. Russotto, M. Chartier, E. De Filippo +89
The elliptic-flow ratio of neutrons with respect to protons in reactions of neutron rich heavy-ions systems at intermediate energies has been proposed as an observable sensitive to…
The FAZIA setup: a review on the electronics and the mechanical mounting
S. Valdré, G. Casini, N. Le Neindre +78
In this paper the technological aspects of the FAZIA array will be explored. After a productive commissioning phase, FAZIA blocks started to measure and give very useful data to ex…
Kinematical coincidence method in transfer reactions
L. Acosta, F. Amorini, L. Auditore +27
A new method to extract high resolution angular distributions from kinematical coincidence measurements in binary reactions is presented. Kinematic is used to extract the center of…
Correlations between isospin dynamics and Intermediate Mass Fragments emission time scales: a probe for the symmetry energy in asymmetric nuclear matter
E. De Filippo, F. Amorini, L. Auditore +31
We show new data from the Ni+Sn and Ni+Sn reactions studied in direct kinematics with the CHIMERA detector at INFN-LNS and compared with the reverse k…
Results of the ASY-EOS experiment at GSI: The symmetry energy at suprasaturation density
P. Russotto, S. Gannon, S. Kupny +89
Directed and elliptic flows of neutrons and light charged particles were measured for the reaction 197Au+197Au at 400 MeV/nucleon incident energy within the ASY-EOS experimental ca…
