Australian Meeting on Accelerator-Based Particle Physics

18 Feb 2019, 08:30 → 19 Feb 2019, 18:30 Australia/Melbourne

S2 Lecture Theatre (Monash University)

Archil Kobakhidze (The University of Sydney), Csaba Balazs (Monash University), German Valencia (Monash University), Jordan Nash (Imperial College (GB)), Paul Douglas Jackson (University of Adelaide), Peter Athron, Peter Skands (Monash University (AU)), Raymond Volkas (The University of Melbourne), Ulrik Egede (Monash University (AU))

This workshop will focus on future directions for the field of accelerator-based particle physics in Australia, and will also serve as a trial for a meeting format to help us keep in touch, enhance collaborations, and co-strategise in the post-CoEPP era. The program will comprise both research talks as well as more strategy oriented sessions focusing on vision and plans.

Note that we plan to start around 10:30 on Monday morning to allow people from out of town to travel down on an early flight. Please email us if you have any questions or input for the workshop organisation.

09:20 Search for new physics using electroweak penguin decays of b-hadrons

Electroweak penguin decays where a b-hadron decays to a final state with two leptons are sensitive to physics beyond the Standard Model up to mass scales around 100 TeV. I will discuss the results of recent LHCb analyses and outline some of the most important analyses to be carried out in the future.

09:40 Anatomy of a six-parameter fit to the b to s l+ l- anomalies

Discrepancies between measurements of decay modes with an underlying quark level transition $b\to s \ell^+\ell^-$ and the corresponding standard model predictions have persisted for several years, particularly for the muon channels. Some of the largest deviations from the SM occur for the low $q^2$ bins of the observable dubbed $P_5^\prime$ as well as for branching ratios for the channel $B_s\to \Phi \mu\mu$, although the anomalies found in $R_K$ and $R_{K^*}$ are also very attractive since they make a case for lepton flavour universality violation. The apparent inadequacy of the SM becomes more compelling from the point of view of a global fit. For example, the authors of arXiv:1704.05340 have described 175 observables in terms of six parameters encoding new physics and have quantified the disagreement with the SM at about the $5\sigma$ level, considering in detail certain one and two parameter fits. In this talk I will discuss the full six-dimensional fit, defining metrics to quantify in detail where the deviations from the SM occur and presenting a visualization of some results in the six-dimensional parameter space. This allows exploring the relation between single observables and the parameter space in the context of the global fit, and in particular also in the context of important correlations between observables.

10:00 Hadron Collider Sensitivity to Fat Flavourful Z′s for RK(∗)

I will discuss the scenario where new physics in the form of a massive Z′ particle explains apparent measurements of lepton flavour non-universality in B→K(∗)l+l− decays. Hadron collider sensitivities for direct production of such Z′s have been previously studied in the narrow width limit for a μ+μ− final state. I will extend the analysis to sizeable decay widths and improve the sensitivity estimate for the narrow width case. I will estimate the sensitivities of the high luminosity 14 TeV Large Hadron Collider (HL-LHC), a high energy 27 TeV LHC (HE-LHC), as well as a potential 100 TeV future circular collider (FCC).

Speaker: Dr Matthew Dolan (University of Melbourne)

10:20 CP Violation measurements at Belle II

Over the next 5 - 10 years the Belle II experiment will collect 50 times more data than predecessor B-Factory experiments. Together with data from LHCb, these enable precision measurements of CP-violation in decays of heavy hadrons and new CP-violation measurements of processes too rare to be investigated to date. Along with commensurate improvements in theory, these provide stringent tests of the Standard Model.

11:00 From HEP to Particle Therapy

CMRP always was an integral part of Australian HEP community and benefited from HEP silicon radiation detector R&D that led to many innovations in proton and Heavy Ion Therapy quality assurance. Talk will overview development at CMRP of innovative silicon radiation detectors utilizing edgeless and 3D silicon detector technology which was originally developed for HEP Si trackers and their application at many particle therapy accelerator facilities around the world. These detectors allowed fast determination of the range of GeV energy range ions and their Radiobiological Efficiency (RBE) without which successful treatment is impossible. Recently the silicon 3D detectors “mushroom” invented and developed at CMRP and fabricated jointly with SINTEF were selected by ESA as the best detector for GCR detection and prediction of SEU in electronics and radiobiological hazard of radiation for astronauts during forthcoming space missions. http://space-env.esa.int/index.php/news-reader/items/tissue-equivalent-crew-dosimeter-based-on-novel- 3d-si-processing.html These detectors were used for benchmarking of Geant 4 in HIT. Collaboration between HEP and Medical Physics communities is important for HEP technology transfer to particle therapy.

11:20 Topological avatars of the Standard Model

With the discovery of the Higgs boson, the perturbative spectrum of the Standard Model is complete. There are new interesting, albeit less explored, physical phenomena associated with a non-perturbative spectrum of the Standard Model, which awaits its discovery at LHC and future colliders. I will discuss few such topological avatars of the electroweak theory focussing on monopoles and sphalerons.

Speaker: Archil Kobakhidze (The University of Sydney)

11:40 Optimising ATLAS searches for supersymmetry

I will present the results of recent Adelaide-Monash collaboration on identifiying supersymmetric models that are currently being missed at the LHC. This includes surprising results that indicate that there is no current constraint on the electroweakino sector of the MSSM. Plans for developing new analyses that tackle this issue will be outlined and placed in the context of ongoing work with former CoEPP international partners.

Speaker: Martin John White (University of Adelaide (AU))
