Pseudo-goldstino and electroweakinos via VBF processes at LHC
The multi-sector SUSY breaking predicts pseudo-goldstino which can couple to
the visible sector more strongly than the ordinary gavitino and thus induce the
decays of the lightest neutralino and chargino (collectively called
electroweakinos) inside the detector. In this note we study the electroweakino
pair productions via vector boson fusion (VBF) processes followed by decays to
pseudo-goldstino at the LHC. Our Monte Carlo simulations show that at the 14
TeV LHC with 3000 fb^{-1} luminosity the dominant production channel
pp->chargino+neutralino+2 jets can have a statistical significance above
2-sigma while other production channels are not accessible.Comment: Version in JHEP (comments added
Diffusion Dynamics, Moments, and Distribution of First Passage Time on the Protein-Folding Energy Landscape, with Applications to Single Molecules
We study the dynamics of protein folding via statistical energy-landscape
theory. In particular, we concentrate on the local-connectivity case with the
folding progress described by the fraction of native conformations. We obtain
information for the first passage-time (FPT) distribution and its moments. The
results show a dynamic transition temperature below which the FPT distribution
develops a power-law tail, a signature of the intermittency phenomena of the
folding dynamics. We also discuss the possible application of the results to
single-molecule dynamics experiments
