The recently published first measurement of charged hadron multiplicity density at mid-rapidity
dNch/d = 1584 ± 4(stat.) ± 76(sys.) in central Pb + Pb collisions at ps = 2.76 TeV by the ALICE Experi...
Heavy-particle formalism with Foldy-Wouthuysen representation
Heavy-particle formalism Foldy-Wouthuysen representation
2010/11/11
We use the Foldy-Wouthuysen representation to construct Lorentz-invariant interactions. The couplings obtained this way feature a straightforward $1/m$ expansion, which ensures Lorentz invariance orde...
Charge stripping accumulation of light heavy ions in HIRFL-CSR main ring
heavy-ion accelerator accumulation stripping injection
2009/8/17
The charge stripping injection method has been adopted for the accumulation of light heavy ions in HIRFL-CSR. This method has some special requirements for the accelerating particles, and at the same ...
