Poster contribution

Following the many contributions KLOE-2 has done to Dark Matter (DM) searches, an alternative model, where the Dark Force mediator is an hypothetical leptophobic B boson, in contra-position to the U boson or "dark photon", is investigated. The B boson couples mainly to quarks and it can be searched in the Phi decay to eta-B where B will decay in p0-gamma. So far, investigation of the pi0-gamma...

213. Search for upward-going air showers with the fluorescence detector of the Pierre Auger Observatory

The fluorescence detector (FD) of the Pierre Auger Observatory is sensitive to upward-going air showers for energies above 10^17 eV. Given its operation time and wide field of view, the FD has the potential to support or constrain the recent "anomalous" observations by the ANITA detector, interpreted as upward-going air showers of unexplained nature.

We have used 14 years of data collected...

175. ATLAS searches for supersymmetry with long-lived particles

tbd

Tau2021 Abstracts

Poster contribution

Various Supersymmetry (SUSY) scenarios, including split SUSY and anomaly or gravity-mediated SUSY-breaking scenarios, lead to signatures with long-lived particles. Searches for these processes may target either the long lived particle itself or its decay products at a significant distance from the collision point. These signatures provide interesting technical challenges due to their special...

174. ATLAS searches for supersymmetry with tau leptons

tbd

Tau2021 Abstracts

Poster contribution

Searches for supersymmetry (SUSY) involving scalar tau leptons (staus) are interesting analyses, well motivated by naturalness and dark matter arguments, for example in coannihilation models. In this talk, an overview of the most recent ATLAS searches using the full Run2 dataset which look for either direct production of staus or production of supersymmetric particles which are assumed to...

172. Search for Higgs boson pair production in the bbtautau final state with the ATLAS detector

tbd

Tau2021 Abstracts

Poster contribution

A search for Higgs boson pair production in events with two b-jets and two τ-leptons is presented, using a proton–proton collision data set with an integrated luminosity of 139/fb collected at sqrt(s) = 13 TeV by the ATLAS experiment at the LHC. Higgs boson pairs produced non-resonantly or in the decay of a narrow-width scalar resonance in the mass range 251 to 1600 GeV are targeted. Events in...

171. Search for lepton flavor violating decays of the Higgs boson with the ATLAS detector

tbd

Tau2021 Abstracts

Poster contribution

Lepton-flavor-violating decays of the Higgs boson are searched for, where an observation would be a clear sign of physics phenomena beyond the Standard Model. Various results for different decays, based on pp collision data collected at 13 TeV, will be presented.

173. Searches for Supersymmetry with the ATLAS detector

tbd

Tau2021 Abstracts

Poster contribution

Supersymmetry (SUSY) provides elegant solutions to several problems in the Standard Model, and searches for SUSY particles are an important component of the LHC physics program. This talk will present the latest results from searches conducted by the ATLAS experiment, covering both strong and electroweak SUSY particle production processes. The searches target multiple final states and...
