Two-pion production in deuteron-deuteron collisions at low energies

Two Pion Production in Nucleon-nucleon Collisions at Intermediate Energies

We have developed a model for the NN → NNππ reaction and evaluated cross sections for the different charged channels. The low energy part of those channels where the pions can be in an isospin zero state is dominated by N∗(1440) excitation, driven by an isoscalar source followed by the decay N∗ → N(ππ) S−wave . At higher energies, and in channels where the pions are not in T=0, ∆ excitation mec...

Results from Phenix on Deuteron and Anti-deuteron Production in Au+au Collisions at Rhic

At the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, protons and gold nuclei have been brought to collide at nucleon-nucleon center-of-mass energies up to √ sNN = 200 GeV. The data this presentation is based on are from Au+Au interactions at the maximum RHIC energy and were accumulated during the second run at RHIC in the year 2001. The results on deuteron and anti-d...

Neutrino-deuteron reactions at solar neutrino energies

In interpreting the SNO experiments, very accurate estimates of the νd reaction cross sections are of great importance. We improve the previous estimates of our group by updating some of its inputs and by taking into account the results of a recent effective-field-theoretical calculation. The new cross sections are slightly (∼1 %) larger than the previously reported values. We present arguments...

Deuteron Photodissociation in Ultraperipheral Relativistic Heavy-Ion on Deuteron Collisions

In ultraperipheral relativistic deuteron on heavy-ion collisions, a photon emitted from the heavy nucleus may dissociate the deuterium ion. We find deuterium breakup cross sections of 1.38 barns for deuterium-gold collisions at a center of mass energy of 200 GeV per nucleon, as studied at the Relativistic Heavy Ion Collider, and 2.49 barns for deuterium-lead collisions at a center of mass energ...
