Deuteron and triton production in Pb + Pb collisions at 158 AGeV

NA44 has measured the invariant cross section of deuterons and tritons at non-zero $p_{T}$ in 158 AGeV lead on lead collisions at CERN SPS. Normalized transverse mass spectra and coalescence parameters versus $p_{T}$ have been calculated showing a significant transverse flow. Radius parameters have...

Descripción
Sumario:NA44 has measured the invariant cross section of deuterons and tritons at non-zero $p_{T}$ in 158 AGeV lead on lead collisions at CERN SPS. Normalized transverse mass spectra and coalescence parameters versus $p_{T}$ have been calculated showing a significant transverse flow. Radius parameters have been extracted using a simple thermal coalescence model. Results from RQMD+coalescence calculations are compared to the data.
