Elastic scattering in geometrical model
; Wibig, Tadeusz
(Elsevier B.V., 2016)
The experimental data on proton–proton elastic and inelastic scattering emerging from the measurements at the Large Hadron Collider, calls for an efficient model to fit the data. We have examined the optical, geometrical ... -
Electrocaloric effect in cubic Hubbard nanoclusters
Balcerzak, Tadeusz; (Springer Nature, 2018)
In the paper a computational study of the electrocaloric efect is presented for a cubic nanocluster consisting of 8 sites. The system of interest is described by means of an extended Hubbard model in external electric ... -
Erratum: Measurement of D^{∗±} production in deep inelastic scattering at HERA
(Springer Berlin Heidelberg, 2014)In the analysis for our paper on D* production, the beauty contribution was erroneously subtracted twice in the extraction of the reduced cross sections. This affected tables 9 and 10 as well as figures 9 and 10 that ... -
Further studies of the photoproduction of isolated photons with a jet at HERA
(Springer Science+Business Media on behalf of the Scuola Internazionale Superiore di Studi Avanzati, 2014)In this extended analysis using the ZEUS detector at HERA, the photoproduction of isolated photons together with a jet is measured for different ranges of the fractional photon energy, x_γ^{meas}, contributing to the ... -
Generalized Niederer’s transformation for quantum Pais–Uhlenbeck oscillator
(Elsevier B.V., 2015)We extend, to the quantum domain, the results obtained in [Nucl. Phys. B 885 (2014) 150] and [Phys. Lett. B 738 (2014) 405] concerning Niederer’s transformation for the Pais–Uhlenbeck oscillator. Namely, the quantum ... -
Hamiltonian formalisms and symmetries of the Pais–Uhlenbeck oscillator
(Elsevier B.V., 2014)The study of the symmetry of Pais–Uhlenbeck oscillator initiated in Andrzejewski et al. (2014) [24] is continued with special emphasis put on the Hamiltonian formalism. The symmetry generators within the original Pais and ... -
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 ... -
“Isochronic” dynamical systems and nullification of amplitudes
; Kosinski, Piotr (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 ... -
Lorentz-covariant, unitary evolution of a relativistic Majorana qubit
Smoliński, Kordian; ; ; (Springer Nature, 2018)
We formulate a covariant description of a relativistic qubit identified with an irreducible set of quantum spin states of a Majorana particle with a sharp momentum. We treat the particle’s four-momentum as an external ... -
Measurement of beauty and charm production in deep inelastic scattering at HERA and measurement of the beauty-quark mass
(Springer Science+Business Media on behalf of the Scuola Internazionale Superiore di Studi Avanzati, 2014)The production of beauty and charm quarks in ep interactions has been studied with the ZEUS detector at HERA for exchanged four-momentum squared 5 < Q^2 < 1000 GeV^2 using an integrated luminosity of 354 pb^{−1}. The ... -
Measurement-induced geometric measures of correlations based on the trace distance for two-qubit X states
Bauer, Jarosław; Walczak, Zbigniew (Springer Nature, 2020)
We apply the modified Brodutch and Modi method of constructing geometric measures of correlations to obtain analytical expressions for measurement-induced geometric classical and quantum correlations based on the trace ... -

Method for Generating of Archimedean Triangular Connective Operators
(Łódzkie Towarzystwo Naukowe, 2018)Archimedean triangular operators form the basis of the tools for development, analysis and designing of fuzzy systems. They are generated by simple, monotone, single-valued and continuous functions. The basic sets of ... -
Modalities for an Allegorical Conceptual Data Model
(MDPI AG, 2014)Allegories are enriched categories generalizing a category of sets and binary relations. In this paper, we extend a new, recently-introduced conceptual data model based on allegories by adding support for modal operators ... -
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 ... -
Multi-objective optimization of vehicle routing problem using evolutionary algorithm with memory
Wiatrowski, Grzegorz; Podlaski, Krzysztof (AGH Publishing House, 2017)
The idea of a new evolutionary algorithm with memory aspect included is proposed to find multiobjective optimized solution of vehicle routing problem with time windows. This algorithm uses population of agents that ... -
Noise resistance of activation of the violation of the Svetlichny inequality
(Springer Nature, 2019)In this paper, we analyze the activation of the violation of the Svetlichny inequality in GHZ states in the presence of noise. We take into account bit flip, phase flip, amplitude damping and depolarizing noisy channels ... -
On the triviality of higher-derivative theories
; Gonera, Joanna; ; Bolonek-Lasoń, Katarzyna (North-Holland, 2012)
The higher-derivative theories with degenerate frequencies exhibit BRST symmetry [V.O. Rivelles, Phys. Lett. B 577 (2003) 147]. In the present Letter meaning of BRST-invariance condition is analyzed. The BRST symmetry is ... -
