Associated $Z^\prime$ production in the flavorful $U(1)$ scenario for $R_{K^{(*)}}$

The flavorful $Z^\prime$ model with its couplings restricted to the left-handed second generation leptons and third generation quarks can potentially resolve the observed anomalies in $R_K$ and $R_{K^*}$. After examining the current limits on this model from various low-energy processes, we probe this scenario at 14 TeV high-luminosity run of the LHC using two complementary channels: one governed by the coupling of $Z'$ to $b$-quarks and the other to muons. We also discuss the implications of the latest LHC high mass resonance searches in the dimuon channel on the model parameter space of our interest.

Cosmic Ray Muography

Muons are fundamental, charged particles that form part of our naturally-occurring background radiation. They are produced in particle showers in the upper atmosphere from the impact of cosmic rays. These muons are incident at sea-level at a rate of about one per square centimetre per minute and with average energies of about 3 GeV - approximately four orders of magnitude more than typical X-rays. Muons are highly penetrating and can traverse hundreds of metres of rock, which has opened up the possibility to use them for challenging imaging applications. Muography is an established technique in volcanology, it has been used to find a cavity in the pyramid of Khufu in Egypt and over the last years a wide variety of applications have been explored – ranging from cargo screening to nuclear waste characterisation and carbon storage monitoring. Lynkeos Technology is a spin-out company from the University of Glasgow, founded in 2016 following a 7-year, £4.8M research programme funded by the NDA. The Lynkeos Muon Imaging System is the worldwide first, CE-marked muon imaging system for the characterization of nuclear waste containers. It has been successfully deployed on the Sellafield site in October 2018. This talk will give an overview of muography applications worldwide and present the activities of Lynkeos Technology in detail, with a focus on the characterization of nuclear waste containers.
