The measurements of the production of two massive vector gauge bosons represent an important test of the Standard Model of particle physics since they probe the structure of the triple gauge boson couplings as well as test of higher-order calculations in quantum chromodynamics. In this talk, a new measurement of the production of WW or WZ boson pairs with one W decaying leptonically and one W...
The focus of this talk is on Z and H boson decays to a pair of tau leptons. The presented analyses use pp collision data collected at center-of-mass energy of 13 TeV.
The top quark is the heaviest known fundamental particle. The measurement of the differential top-quark pair production cross-section provides a stringent test of advanced perturbative QCD calculations. The ATLAS collaboration has performed detailed measurements of those differential cross sections at a centre-of-mass energy of 13 TeV. This talk focuses on differential cross-section...
In this talk, an inclusive search for Supersymmetry is presented. The search is performed in events containing a single lepton, multiple jets, and missing transverse energy in the final state. The proton-proton collision data were recorded by the CMS experiment during Run 2 of the LHC at a center-of-mass energy of 13 TeV. Selections on b-jet enriched and depleted regions target different...
During the last two years the LHC produced pp collisions at the record center-of-mass energy of 13 TeV. The sensitivity of searches for new phenomena with a high mass scale greatly benefited from the energy increase with respect to the LHC run-1 data. Events with two hadronic jets in the final state are of particular interest: new phenomena produced in parton collisions are likely to produce...
A search for the pair production of gluinos decaying to sbottom and stop at the LHC is reported. It utilises the pp collisions of the LHC Run2 dataset collected with the ATLAS detector. The search targets final states containing several energetic jets, of which at least three must be b-tagged, large missing transverse energy and either zero or at least one charged lepton.
Constraints on New Theories Using Rivet (Contur), is a new program designed to utilise precision detector corrected measurements of SM processes at the LHC as a test for physics beyond the standard model. In this talk the methodology and design of Contur is introduced, alongside a brief review of the advantages and limitations of the process. Future directions of the project will also be motivated.
We evaluate the fine-tuning of the phenomenological minimal supersymmetric standard model (pMSSM). We show that, contrary to common believe, that the fine-tuning of the pMSSM is not large yet, nor under pressure by LHC searches. Low sbottom, stop and gluino masses turn out to be less relevant for low fine-tuning than commonly assumed. Fine-tuning arguments point to models with a dark matter...
The Belle II experiment is located at the KEK High Energy Accelerator Research Organization in Tsukuba, Japan.
It is designed to perform measurements in all fields of heavy flavour physics, including measurements of rare B decays.
This talk presents the recent progress in the hadronic and semileptonic tagging algorithm, current sensitivity studies
for the future measurement of $B^+ \rightarrow...
Searches for new physics in events with multiple jets and large missing transverse momentum are sensitive to a broad set of R-parity conserving SUSY models at the LHC. These searches rely on having an accurate prediction for the QCD background, especially when probing regions of the models with compressed spectra and/or regions featuring the production of light-flavor jets. A method for...
Supersymmetry (SUSY) is one of the most promising candidates to solve multiple problems with the Standard Model. In particular models with a compressed mass spectrum are highly motivated by naturalness arguments and cosmological constraints on the dark matter relic density. In this talk, a search for SUSY with a compressed mass spectrum using events with a high-momentum jet from initial state...
Dark matter self-interactions are frequently used in the explanation of small structure problems in the universe. Depending on the model and strength of the interactions they can have important implications on the formation of structures, from dwarf galaxies to large galaxy clusters. Using four generic dark matter toy models, we present the effects of inelastic processes (i.e. dark...
