The concept of Existence and the derivation of a Quantum Force

Autor: Costa, C. G. S.

We define a new dynamical variable, the relative existence e, in terms of space and time. Taking it as a generalized positional coordinate, we show that for conservative systems the canonically conjugated momentum is identified as the classical force

The prompt TeV-PeV atmospheric neutrino window

Autor: Costa, C. G. S., Halzen, F., Salles, C.

Publikováno v: Phys.Rev. D66 (2002) 113002

We discuss the possible existence of an observational window, in the TeV-PeV energy range, for the detection of prompt neutrinos from the decay of charmed particles produced in cosmic ray interactions with the atmosphere. We calculate the event rates

Composition of Primary Cosmic Rays Beyond the 'Knee'from Emulsion Chamber Observations

Autor: Costa, C. G. S., Halzen, F., Bellandi, J., Salles, C.

Publikováno v: Phys.Rev. D54 (1996) 5558-5562

We show that the simplest assumptions for the dynamics of particle production allow us to understand the fluxes of hadrons and photons at mountain altitudes as well as the structure of individual events. The analysis requires a heavy nuclear componen

We report on a search for electromagnetic and/or hadronic showers (cascades) induced by a diffuse flux of neutrinos with energies between 5 TeV and 300 TeV from extraterrestrial sources. Cascades may be produced by matter interactions of all flavors
