Dynamics of the peel front and the nature of acoustic emission during peeling of an adhesive tape
We investigate the peel front dynamics and acoustic emission of an adhesive
tape within the context of a recent model by including an additional
dissipative energy that mimics bursts of acoustic signals. We find that the
nature of the peeling front can vary from smooth to stuck-peeled configuration
depending on the values of dissipation coefficient, inertia of the roller, mass
of the tape. Interestingly, we find that the distribution of AE bursts shows a
power law statistics with two scaling regimes with increasing pull velocity as
observed in experiments. In this regimes, the stuck-peeled configuration is
similar to the `edge of peeling' reminiscent of a system driven to a critical
state.Comment: Accepted for publication in Phys. Rev. Let
Higgs self coupling measurement in e+e- collisions at center-of-mass energy of 500 GeV
Feasibility of the measurement of the trilinear self-couplings of the Higgs
boson is studied. Such a measurement would experimentally determine the
structure of the Higgs potential. Full hadronic and semi-leptonic final states
of the double-Higgs strahlung have been investigated.Comment: 10 pages, 5 tables, 8 figure
