Quantum Reflection of S-wave Unstable States
N. G. Kelkar
The phase time in quantum tunneling can be disentangled into a dwell time plus a term arising due to the interference of the reflected and incident waves in front of the barrier. T…
Hadronic Molecules and the f0(980)/a0(980)
Tanja Branz, Thomas Gutsche, Valery E. Lyubovitskij
We discuss a possible interpretation of the f0(980) and a0(980) mesons as hadronic molecules - bound states of K and Kbar mesons. Using a phenomenological Lagrangian approach we ca…
Microscopic calculation of the decay of Jaffe-Wilczek tetraquarks, and the Z(4433)
Marco Cardoso, Pedro Bicudo
Here the tetraquarks are studied a la Jaffe and Wilczek. The decay width is fully computed with a microscopic quark model, using the resonating group method.
Searching for the Scalar Glueball
Wolfgang Ochs
Existence of gluonic resonances is among the early expectations of QCD. Today, QCD calculations predict the lightest glueball to be a scalar state with mass within a range of about…
Effect of Pions in Cosmic Rays
P. Castelo Ferreira, J. Dias de Deus
The effects of pions for vacuum polarization in background magnetic fields are considered. The effects of quark condensates is also briefly addresses. Although these effects are ou…
New (and Old) Perspectives on Higgs Physics
John F. Gunion
Old and new ideas regarding Higgs physics are reviewed. We first summarize the quadratic divergence / hierarchy problem which strongly suggests that the SM Higgs sector will be sup…
