On Regge kinematics in SCET
We discuss the kinematics of the particles that make up a Reggeon in field
theory, using the terminology of the Soft Collinear Effective Theory (SCET).
Reggeization sums a series of strongly-ordered collinear emissions resulting in
an overall Reggeon exchange that falls in the Glauber or Coulomb kinematic
region. This is an extremely multi-scale problem and appears to fall outside of
the usual organizing scheme of SCET.Comment: 7 pages, 3 figure
Production of {\pi}+ and K+ mesons in argon-nucleus interactions at 3.2 AGeV
First physics results of the BM@N experiment at the Nuclotron/NICA complex
are presented on {\pi}+ and K+ meson production in interactions of an argon
beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse
momentum distributions, rapidity spectra and multiplicities of {\pi}+ and K+
mesons are measured. The results are compared with predictions of theoretical
models and with other measurements at lower energies.Comment: 29 pages, 20 figure
