This paper, in addition to our recent works, intends to explore the behavior of the Wetterich flow equations in the portion of the theory space spanned by non-branching melons constrained with Ward-identities. We focus on a rank-5 just-renormalizable

Renormalization in Minkowski space-time
Autor: I. Steib, Janos Polonyi, Sándor Nagy

Int.J.Mod.Phys.A, 2021, 36 (05), pp.2150031. ⟨10.1142/S0217751X21500317⟩
The multiplicative and the functional renormalization group methods are applied for the four dimensional scalar theory in Minkowski space-time. It is argued that the appropriate choice of the subtraction point is more important in Minkowski than in E

A Simple Expression for Heavy to Light Meson Semileptonic Decays Form Factors
Autor: T. N. Pham
Publikováno v: Int.J.Mod.Phys.A
Int.J.Mod.Phys.A, 2018, 33 (28), pp.1850160. ⟨10.1142/S0217751X18501609⟩
Like the two-photon and two-gluon decays of the $P$-wave $\chi_{c0,2}$ and $\chi_{b0,2}$ charmonium state for which the Born term produces a very simple decgays amplitude in terms of an effective Lagrangian with two-quark local operator, the Born ter

The renormalization group equations revisited

Int.J.Mod.Phys.A, 2018, 33 (26), pp.1830024. ⟨10.1142/S0217751X18300247⟩
Starting from a well defined local Lagrangian, we analyze the renormalization group equations in terms of the two different arbitrary scales associated with the regularization procedure and with the physical renormalization of the bare parameters, re

International audience; We revisit the thermodynamic behavior of the random-anisotropy O(N) model by investigating its large-N limit. We focus on the system at zero temperature where the mean-field-like artifacts of the large-N limit are less severe.

Physical Review D, 2015, 92 (7), pp.076009. ⟨10.1103/PhysRevD.92.076009⟩
We study a $\phi^4$-theory at finite temperature in a finite volume. Quantum, thermal and volume fluctuations are treated with the functional renormalisation group. Specifically, we focus on the interplay of temperature and length scales driving the
