Quantum and q-deformed algebras find their application not only in mathematical physics and field theoretical context, but also in phenomenology of particle properties. We describe (i) the use of quantum algebras Uq(sun) corresponding to Lie algebras of the groups SUn, taken for flavor symmetries of hadrons, in deriving new high-accuracy hadron mass sum rules, and (ii) the use of (multimode) q-...

We review theoretical and experimental advances in the application of the perturbative QCD approach to the description of particle distributions in jets in the (semi) soft region with particular emphasis on HERA physics.

We briefly review the distinctive signals of brane world models with low tension. We pay special attention to the brane fluctuations (branons), whose phenomenological consequences could be important both in high energy particle physics experiments and in astrophysical and cosmological observations. ∗Proceedings of the 29th Bienal Real Sociedad Española de F́ısica on the centennial of the society...
