We implement scalar and vector leptoquark (LQ) models in the universal FeynRules output (UFO) format assuming the Standard Model fermion content and conservation of baryon and lepton numbers. Scalar LQ implementations include next-to-leading order (NLO) QCD corrections. We report the NLO QCD inclusive cross sections in proton-proton collisions at 13 TeV, 14 TeV, and 27 TeV for all on-shell LQ production processes. These comprise (i) LQ pair production (pp → ΦΦ) and (ii) single LQ + lepton production (pp → Φℓ) for all initial quark flavours (u, d, s, c, and b). Vector LQ implementation includes adjustable non-minimal QCD coupling. We discuss several aspects of LQ searches at a hadron collider, emphasising the implications of SU(2) gauge invariance, electroweak and flavour constraints, on the possible signatures. Finally, we outline the high-pT search strategy for LQs recently proposed in the literature to resolve experimental anomalies in B-meson decays. In this context, we stress the importance of complementarity of the three LQ related processes, namely, pp → ΦΦ, pp → Φℓ, and pp → ℓℓ.

Objective of the paper is to present lung cancer as preventable disease based on epidemiological, molecular and genomic data. Lung cancer is the most deadly malignancy around the world, both in male and female population. Vast majority of lung cancers (close to 90%) are directly caused by cigarette smoking, and thus present one of the most preventable deadly disease in humanity. Analysis of history of cigarette consumption and rise of lung cancer as world epidemics. Review of efforts to fight tobacco epidemics and how it influences incidence and prevalence of the lung cancer. Investigation of the effects of cigarette smoking on health and economic status of Bosnia and Hercegovina. Tobacco epidemics and lung cancer can be prevented. Goal is to exterminate cigarette smoking. That can be achieved only concerted effort by members of family, patients themselves, physicians, researchers, non-governmental organizations, political figures and society as a whole. CONCLUSION In country like Bosnia and Herzegovina first step is to inform society about devastating effects of cigarette smoking. Best practices already exist and initial goal should be to start using them.
