Phenomenology of an extended IDM with loop-generated fermion mass hierarchies
We perform a comprehensive analysis of the most distinctive and important
phenomenological implications of the recently proposed mechanism of sequential
loop generation of strong hierarchies in the Standard Model (SM) fermion mass
spectra. This mechanism is consistently realized at the level of renormalizable
interactions in an extended variant of the Inert Higgs Doublet model,
possessing the additional discrete and
gauge family symmetries, while the matter sectors of the SM are extended by
means of -singlet scalars, heavy vector-like leptons and quarks, as
well as right-handed neutrinos. We thoroughly analyze the most stringent
constraints on the model parameter space, coming from the
collider searches, related to the anomaly in lepton universality, and the muon
anomalous magnetic moment, as well as provide benchmark points for further
tests of the model and discuss possible "standard candle" signatures relevant
for future explorations.Comment: Version accepted for publication in EPJC. arXiv admin note: text

Defectos de la terminología en la ley y la técnica
The article deals with the formation of parallel different concepts that complicate the understanding of terms and categories used in the process of enforcement. Violation of the requirements to the concept formulation or to the selection of terms for their designation relates to the conceptual and logical and linguistic defects respectively.El artículo aborda la formación de diferentes conceptos paralelos que complican la comprensión de los términos y categorías utilizados en el proceso de aplicación. La violación de los requisitos para la formulación del concepto o la selección de términos para su designación se relacionan con los defectos conceptuales y lógicos y lingüísticos, respectivamente
UTVRĐIVANJE UČINKOVITOSTI EKSPLOZIVA KOD IZVOĐENJA MINIRANJA
Experimental methods for determining a performance index of explosives are analysed: the methods of a ballistic pendulum, ballistic mortar, a lead block, and according to the volume of soil explosion funnel. It is defined that the determination of a performance index of emulsion explosives (EE) involves a set of significant features connected with a large critical diameter requiring the experiments with large-mass charges and resulting in refusal from the traditional methods of determining a performance index. Analytical methods for calculating an index of relative performance of explosives are analysed. Determination of the performance indices of explosives with the help of analytical methods helps identify considerable differences in the calculation results; in case of emulsion explosives the results are erroneously low at all. It is since analytical methods do not consider the brisant action of emulsion explosives. This paper represents the developed methodology of determining a performance index of explosives according to the degree of detonation velocity. The proposed methodology considers the key energy and detonation characteristics of explosives: heat and volume of the explosion products, density (thickness), and detonation velocity. The use of analytical methodology for calculating a performance index for all explosive types makes it possible to get correct results that are necessary for designing the parameters of drilling and blasting operations.U radu su analizirane eksperimentalne metode kojima se određuje indeks učinkovitosti eksploziva: metoda balističkoga klatna, metoda balističkoga mužara, Trauzlova proba i metoda određivanja volumena kratera od miniranja u tlu. Utvrđeno je kako određivanje indeksa učinkovitosti emulzijskih eksploziva (EE) uključuje skupinu važnih značajki povezanih s velikim kritičnim promjerom, a to zahtijeva ispitivanja s nabojima velike mase i odustajanje od tradicionalnih metoda određivanja indeksa učinkovitosti. Također, analizirane su analitičke metode za izračunavanje indeksa relativnoga učinka eksploziva. Određivanje indeksa učinkovitosti eksploziva uz pomoć analitičkih metoda pomaže identificirati znatne razlike u rezultatima, a rezultati su u slučaju emulzijskih eksploziva općenito preniski. Do toga dolazi zato što analitičke metode ne uzimaju u obzir brizantno djelovanje emulzijskih eksploziva. U radu je prikazana razvijena metodologija određivanja indeksa učinkovitosti eksploziva prema stupnju brzine detonacije. Predložena metodologija razmatra ključne parametre energije i detonacijskih svojstava eksploziva: toplinu i volumen produkata eksplozije, gustoću (promjer) i brzinu detonacije. Korištenje analitičke metodologije izračuna indeksa učinkovitosti kod svih vrsta eksploziva omogućuje dobivanje točnih rezultata potrebnih za određivanje parametara bušenja i miniranja

Sequentially loop-generated quark and lepton mass hierarchies in an extended Inert Higgs Doublet model
Extended scalar and fermion sectors offer new opportunities for generating
the observed strong hierarchies in the fermion mass and mixing patterns of the
Standard Model (SM). In this work, we elaborate on the prospects of a
particular extension of the Inert Higgs doublet model where the SM hierarchies
are generated sequentially by radiative virtual corrections in a fully
renormalisable way, i.e. without adding any non-renormalisable Yukawa terms or
soft-breaking operators to the scalar potential. Our model has a potential to
explain the recently observed and anomalies, thanks to
the non universal assignments of the fermionic fields that yield non
universal couplings to fermions. We explicitly demonstrate the
power of this model for generating the realistic quark, lepton and neutrino
mass spectra. In particular, we show that due to the presence of both
continuous and discrete family symmetries in the considered framework, the top
quark acquires a tree-level mass, lighter quarks and leptons get their masses
at one- and two-loop order, while neutrino masses are generated at three-loop
level. The minimal field content, particle spectra and scalar potential of this
model are discussed in detail.Comment: 19 pages, 3 figures. Published versio
