title: "Diff. XS $|\eta(b_{1}^{add})|$ in $≥4b$" of "Measurement of $t\bar{t}$ production in association with additional $b$-jets in the $e\mu$ final state in proton-proton collisions at $\sqrt{s}$=13 TeV with the ATLAS detector"

description: The measured normalised differential cross-section as a function of $|\eta(b_{1}^{\text{add}})|$ in the $e\mu+\geq4b$ phase space. The overflow is included in the last bin.
description: This paper presents measurements of top-antitop quark pair $t\bar{t}$ production in association with additional $b$-jets. The analysis utilises 140fb$^{-1}$ of proton--proton collision data collected with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13TeV. Fiducial cross-sections are extracted in a final state featuring one electron and one muon, with at least three or four $b$-jets. Results are presented at the particle level for both integrated cross-sections and normalised differential cross-sections, as functions of global event properties, jet kinematics, and $b$-jet pair properties. Observable quantities characterising $b$-jets originating from the top quark decay and additional $b$-jets are also measured at the particle level, after correcting for detector effects. The measured integrated fiducial cross-sections are consistent with $t\bar{t}b\bar{b}$ predictions from various next-to-leading-order matrix element calculations matched to a parton shower within the uncertainties of the predictions. State-of-the-art theoretical predictions are compared with the differential measurements; none of them simultaneously describes all observables. Differences between any two predictions are smaller than the measurement uncertainties for most observables.

title: THE PROBLEM OF OZONE HOLES IN NATURE

description: This thesis highlights the depletion of the ozone layer in the stratosphere, the anthropogenic factors causing it, and their consequences. It also demonstrates the intensification of ultraviolet radiation resulting from ozone thinning and its negative impact on human health and the environment. Furthermore, the significance of the Montreal Protocol and the prospects for the recovery of the ozone layer are briefly discussed.
