Results are presented on structure functions and final state properties within the CCFM approach. Traditionally used forms of the CCFM equation have difficulty fitting the F 2 data, predicting too fast a growth at small x. A solution can be found in a particular treatment of formally subleading (1 − z) terms, which dampens very considerably the small-x growth. Preliminary results are shown for ...

We calculate the probability of destruction of a metastable string by collisions of the Goldstone bosons, corresponding to the transverse waves on the string. We find a general formula that allows to determine the probability of the string breakup by a collision of arbitrary number of the bosons. We find that the destruction of a metastable string takes place only in collisions of even number o...

Photoproduction events which have two or more jets with transverse energy E T > 4:5 GeV have been studied in the p centre of mass energy range 158 GeV < W < 247 GeV with the H1 detector at HERA. The fraction f (() of events with a rapidity gap between the two highest E T jets is measured as a function of the rapidity separation between the jet axes. A gap is deened as the absence between the je...

We calculate the distribution of transverse energy, QΩ, radiated into an arbitrary interjet angular region, Ω, in high-pT two-jet events. We find a distribution that can be extrapolated smoothly to QΩ = ΛQCD, where it vanishes. This method provides a class of predictions on transverse energy radiated between jets, as a function of jet energy and rapidity, and of the choice of the region Ω in wh...

The governing equations of a transversely isotropic dissipative medium are solved analytically to obtain the surface wave solutions. The appropriate solutions satisfy the required boundary conditions at the stress-free surface to obtain the frequency equation of Rayleigh wave. The numerical values of the non-dimensional speed of Rayleigh wave speed are computed for different values of frequency...

  Nonlinear Dust lattice modes are studied in a hexagonal two-dimensional dusty plasma lattice, in presence of charge gradient of dust particles. In this lattice, such gradients affect nonlinear behavior of dust lattice waves. The amplitude modulation of off-plane transverse dust lattice wave packets is investigated considering the anisotropy of interactions, caused by the height-dependent char...

The jet shape modification due to partonic energy loss in the dense QCD matter is investigated by the help of the special transverse energy-energy correlator in the vicinity of maximum energy deposition of every event. In the accepted scenario with scattering of jet hard partons off comoving medium constituents this correlator is independent of the pseudorapidity position of a jet axis and beco...

We give a short overview of the phenomenology of azimuthal and transverse single spin asymmetries in (un)polarized high-energy hadronic collisions. We briefly summarize a transverse momentum dependent, generalized parton model approach to these polarization phenomena, and discuss some of its applications. Finally, open points and future developments will be outlined.
