Study of the doubly charmed tetraquark [Formula: see text]. [PDF]
Nature Communications, 2021 Quantum chromodynamics, the theory of the strong force, describes interactions of coloured quarks and gluons and the formation of hadronic matter. Conventional hadronic matter consists of baryons and mesons made of three quarks and quark-antiquark pairs,

A class of solutions of the equation d(n²) = d(φ(n)) [PDF]
Notes on Number Theory and Discrete Mathematics, 2023 For any positive integer n let d(n) and φ(n) be the number of divisors of n and the Euler's phi function of n, respectively. In this paper we present some notes on the equation d(n²) = d(φ(n)).

Double-charm heptaquark states composed of two charmed mesons and one nucleon [PDF]
Physical Review D, 2022 Inspired by the experimental discoveries of $T_{cc}$, $\Sigma_c(2800)$, and $\Lambda_c(2940)$ and the theoretical picture where they are $DD^*$, $DN$, and $D^*N$ molecular candidates, we investigate the double charm heptaquark system of $DD^*N$.

The mean value of the function d(n)/d*(n) in arithmetic progressions [PDF]
Notes on Number Theory and Discrete Mathematics, 2023 Let d(n) and d*(n) be, respectively, the number of divisors and the number of unitary divisors of an integer n≥1. A divisor d of an integer is to be said unitary if it is prime over n/d.

Микротопонимы городa-завода Ижевск как источник изучения его удмуртской предыстории [Microtoponyms of the City-Factory of Izhevsk as a Source for Study of its Udmurt Prehistory] [PDF]
Linguistica Uralica, 2021 The present article aims to study the microtoponyms of Izhevsk in a wide historical and cultural context in order to consider the content of the Udmurt component in the cityâs prehistory. Special attention is paid to the etymology of hydronyms (Ðж, Ð

SOME BIOLOGICAL FEATURES OF THE CRUSTACEAN TYPOGRAPHER
International Journal of Advanced Research, 2023 The article presents bark-eating typographus (Ips typographus), i.e., the big spruce bark-eater, which is one of the most dangerous pests, living mainly on spruce, in most cases on sochi and pine (Ð.Д. МаÑлов-2002), rarely on cedar and larch.

Conformal manifolds and 3d mirrors of (D n , D m ) theories
Journal of High Energy Physics, 2022 The Argyres-Douglas (AD) theories of type (D n , D m ), realized by type IIB geometrical engineering on a single hypersurface singularity, are studied. We analyze their conformal manifolds and propose the 3d mirror theories of all theories in this class ...

All basic quantizations of $$D=3$$ D = 3 , $$N=1$$ N = 1 Lorentz supersymmetry
European Physical Journal C: Particles and Fields, 2023 By the supersymmetrization of a simple algebraic technique proposed in Lukierski and Tolstoy (Eur Phys J C 77:226, 2017) we obtain the complete classification of all basic (nonisomorphic) quantum deformations for the orthosymplectic Lie superalgebra ...

$$\theta $$ θ -diagram technique for $${\mathcal {N}}=1$$ N = 1 , $$d=4$$ d = 4 superfields
European Physical Journal C: Particles and Fields, 2023 We describe a diagrammatic procedure to carry out the Grassmann integration in super-Feynman diagrams of 4d theories expressed in terms of $${\mathcal {N}}=1$$ N = 1 superfields. This method is alternative to the well known D-algebra approach. We develop

Названия мать-и-мачехи в удмуртских диалектах [The Names for Coltsfoot (Tussilago farfara L.) Used in Udmurt Dialects]; pp. 53-62 [PDF]
Linguistica Uralica, 2018 In this article the Udmurt dialect names for coltsfoot (Tussilago farfara L.) are discussed, their word-formation structure is analyzed, the etymology of their components is given and the basic naming principles are defined.
