In the Standard Model, the origin of CP-violation lies in the charged weak interaction sector, which involves transitions amongst quarks of different flavor and charge through the emission of a virtual W . The coupling strengths of these transitions for the 3 generations of quarks form a 3×3 matrix first introduced by M. Kobayashi and T. Maskawa and known as the (CKM) matrix. The CKM matrix is ...

We propose an experimental procedure to find out the medium modifications of the φ meson. The reaction is inclusive φ photoproduction in nuclei, looking for KK pairs from the φ decay with total momentum smaller than 100-150 MeV/c, which are made possible at energies of present laboratories from center of mass φ backward production and the help of Fermi motion. We have conducted a many body calc...

In this study, beginning and today expansion of universe are viewed in f(R,Φ,X) gravity. Field equations their solutions Friedmann-Lemaître-Robertson-Walker cosmologies with perfect fluid obtained by considering f(R,Φ,X)=f_0 R+f_1 X^q-V(Φ) model. Validity both gravity model for non-static space-time geometries is discussed making use the matter dynamics results such as pressure energy density. ...

A strong edge-coloring φ of a graph G assigns colors to edges such that φ(e1)≠φ(e2) whenever e1 and e2 are at distance no more than 1. It is equivalent proper vertex coloring the square line G. In 1990 Faudree, Schelp, Gyárfás, Tuza conjectured if bipartite with maximum degree 3 sufficiently large girth, then has most 5 colors. 2021 this conjecture was disproved by Lužar, Mačajová, Škoviera, So...

A subset X of a finite group G is said to be prime-power-independent if each element in has prime power order and there no proper Y with 〈Y,Φ(G)〉=〈X,Φ(G)〉, where Φ(G) the Frattini subgroup G. Bpp all generating sets for have same cardinality. We prove that, Bpp, then solvable. Pivoting on some recent results Krempa Stocka (2014); (2020), this yields complete classification Bpp-groups.

We consider the notion of a Φ-zero divisor, where Φ is Young function, on discrete group. extend some results about p-divisors free groups by Linnell and Puls to divisors.

We find the best possible constant C in inequality‖φ‖Lrpr⩽C‖φ‖Lppr‖φ‖BMO1−pr for all values of parameters p and r such that 1⩽p<r<+∞. To solve problem, we define explicitly compute corresponding Bellman function. This function depends on three variables has a rather complicated structure. first problem an interval then transfer our results to circle line. also obtain explicit estimates several ...
