“Isochronic” dynamical systems and nullification of amplitudes
(North-Holland, 2003)
We construct the set of theories which share the property that the tree-level threshold amplitudes nullify even if both initial
and final states contain the same type of particles. The origin of this phenomenon lies in ...
Hidden Lorentz symmetry of the Hořava–Lifshitz gravity
(North-Holland, 2014)
In this Letter it is shown that the Hořava–Lifshitz gravity theory admits Lorentz symmetry preserving preferred global time foliation of the spacetime.
Induced gravity and gauge interactions revisited
(North-Holland, 2009)
It has been shown that the primary, old-fashioned idea of Sakharov's induced gravity and gauge interactions, in the “one-loop dominance” version, works astonishingly well yielding phenomenologically reasonable results. As ...
Scaling violation and the inelasticity of very high energy proton–proton interactions
(North-Holland, 2011)
The pseudorapidity measurements at LHC, although in the central region only, allows us to perform preliminary tests of the multiparticle production extrapolation formula inspired by the analysis of recent cosmic ray data. ...
Perturbative quantum damping of cosmological expansion
(North-Holland, 2014)
Perturbative quantum gravity in the framework of the Schwinger–Keldysh formalism is applied to compute lowest-order corrections to expansion of the Universe described in terms of the spatially flat Friedman–Lemaître–Robe ...
Modification of thin films induced by slow heavy ions analysed with PIXE and SRIM
(Springer, 2015-03-17)
In the present work the particle induced X-rays (PIXE) emitted during interaction of inert and active slow heavy (HI) ions with specially prepared thin films were measured. Kinematics of the interaction was simulated ...
Badania warstw związków organicznych o właściwościach paramagnetycznych z uwzględnieniem procesu samoorganizacji i badań materiałów biologicznych
(2015)
W pracy przedstawiono badania paramagnetycznych rodników nitroksylowych oraz znakowanych spinowo polipeptydów zaadsorbowanych na dobrze zdefiniowanych powierzchniach. Wyniki eksperymentalne zostały uzyskane przy pomocy ...
Modelowanie procesów radiacyjnych wysokich energii w układach podwójnych gwiazd i ich otoczeniu
(2015)
Wyniki obserwacji układów podwójnych gwiazd niektórych typów, przeprowadzone w zakresie promieniowania gamma, wskazują na istotną rolę procesów wysokich energii wewnątrz tych układów lub w ich otoczeniu. Zaobserwowano ...
Conformal Newton–Hooke symmetry of Pais–Uhlenbeck oscillator
(North-Holland, 2014)
It is demonstrated that the Pais–Uhlenbeck oscillator in arbitrary dimension enjoys the l -conformal Newton–Hooke symmetry provided frequencies of oscillation form the arithmetic sequence ωk=(2k−1)ω1, where k=1,…,n, and ...
