Relativistic configuration-interaction density functional theory: Nonaxial effects on nuclear $ββ$ decay [PDF]
Science Bulletin 69, 2017-2020 (2024), 2023 The relativistic configuration-interaction density functional theory is developed for even-even and odd-odd nuclei and is used to predict the nuclear matrix element of the neutrinoless $\beta\beta$ ($0\nu\beta\beta$) decay in nucleus $^{76}$Ge, amongst the most promising $\beta\beta$-decay candidates.

Nielsen's beta function and some infinitely divisible distributions [PDF]
Mathematische Nachrichten, 2019 We show that a large collection of special functions, in particular Nielsen's beta function, are generalized Stieltjes functions of order 2, and therefore logarithmically completely monotonic.

The five-loop Beta function for a general gauge group and anomalous dimensions beyond Feynman gauge [PDF]
Journal of High Energy Physics, 2017 We focus on a non-abelian gauge field coupled to a single (but general) representation of a family of Nf fermions. By using the same machinery that had allowed us to evaluate the sub-leading large-Nf term of the five-loop Beta function earlier, we here ...

On generalized $\mathtt{k}$-fractional derivative operator
AIMS Mathematics, 2020 The principal aim of this paper is to introduce $\mathtt{k}$-fractional derivative operator by using the definition of $\mathtt{k}$-beta function. This paper establishes some results related to the newly defined fractional operator such as the Mellin ...

Fate of a recent conformal fixed point and $\beta$-function in the SU(3) BSM gauge theory with ten massless flavors [PDF]
Proceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2018 SU(3) gauge theory with $N_f$ fermions in the fundamental representation serves as a theoretical testing ground for possible infrared conformal behavior, which could play a role in BSM composite Higgs models.

The Numerical Evaluation Methods for Beta Function
Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2022 In this study, the beta function that is encountered in computational mathematics and physics is analyzed. The correct evaluation of this function also affects the accuracy of other mathematical functions in quantum mechanical calculations. Especially in

Gauge contribution to the 1/NF expansion of the Yukawa coupling beta function [PDF]
Journal of High Energy Physics, 2017 We provide a closed analytical form for the gauge contribution to the beta function of a generic Yukawa coupling in the limit of large NF , where NF is the number of heavy vector-like fermions charged under an abelian or non-abelian gauge group.

Journal of New Theory, 2022 The main objective of this paper is to use the newly proposed $(p,q;l)$-extended beta function to introduce the $(p,q;l)$-extended $τ$-Gauss hypergeometric and the $(p,q;l)$-extended $τ$-confluent hypergeometric functions with some of their properties ...
