On the reflectivity of surfaces with thin transition or contaminated layers

R. M. Fechtchenko, +3 more
- 01 Jan 2000 - 
TL;DR: In this paper, a correction in terms of the integral characteristics of this deviation is obtained and it is valid ifa sin δ<λ, wherea is the depth of the contaminated layer, and λ and δ are the wavelength and grazing angle of the incident beam, respectively.
Journal ArticleDOI

Search for heavy resonances decaying to ZZ or ZW and axion-like particles mediating nonresonant ZZ or ZH production at $$ \sqrt{s} $$ = 13 TeV

Armen Tumasyan, +2288 more
- 01 Apr 2022 - 
TL;DR: In this article , a search has been performed for heavy resonances decaying to ZZ or ZW and for axion-like particles mediating nonresonant ZZ and ZH production, in final states with two charged leptons ($\ell$ = e, $\mu$) produced by the decay of a Z boson.
Journal ArticleDOI

Measurement of $CP$ asymmetries in $D^{\pm} ightarrow \eta^{\prime} \pi^{\pm}$ and $D_s^{\pm} ightarrow \eta^{\prime} \pi^{\pm}$ decays

Gregory Ciezarek, +773 more

Journal ArticleDOI

arXiv : Searches for 25 rare and forbidden decays of $D^+$ and $D_s^+$ mesons

Roel Aaij, +1006 more
- 31 Oct 2020 - 
TL;DR: In this article, a search is performed for rare and forbidden charm decays of the form $D(s)}+ \to h^\pm \ell^+ \ell^{(\prime)\mp}, where $h^\mm$ is a pion or kaon and $\ell^{(')\pm}$ is an electron or muon.
Journal ArticleDOI

Effect of resonance radiative processes on the amplification factor

T. Ya. Popova, +1 more
- 01 Jun 1970 - 
TL;DR: In this paper, the optimal conditions to achieve amplification without inversion in three-level schemes based on quantum nonlinear interference effects are analyzed and specific features of relaxation processes in optical transitions seting these conditions apart from those in microwave schemes are outlined.
