Description
This event is a "mini open day" where the DESY particle physics department (FH) gives people from other departments the opportunity to get to know us. We would like to present our particle physics activities and our fascination for it. Not "only" the big questions but also our techniques, algorithms etc. -- the other cool stuff. Please register your proposed poster or the tour you want to offer (see guidelines on the abstract submission page) . The orga team will then get back to you with details.

      The ALPS II Experiment
      The second iteration of the Any Light Particle Search (ALPS II) is a light-shining-through-a-wall experiment at DESY which aims to detect laboratory-generated weakly interacting slim particles (WISPs). One such hypothetical particle is the axion-like particle, a dark matter candidate hinted at by astrophysical observations. ALPS II, currently under construction in the tunnel at HERA North, will achieve novel sensitivity to these elusive particles.
      Speakers: Mr Richard Smith (DESY), Mr Rikhav Shah (Uni Mainz, DESY), Mr Todd Kozlowski (University of Florida)

      The MADMAX Experiment
      MADMAX is an experiment to search for dark matter axion in the mass range of 40 µeV to 400 µeV. The challenge is to place a series of parallel 1.25m diameter disks with high planarity (~10 µm) at an environment of 4 K and in a 9 T magnetic dipole field parallel to the disks. A magnet of this size never has built.

      POSTER: Introduction to the ATLAS detector
      ATLAS is a multipurpose detector at CERN for observing proton-proton collisions produced by the LHC. Sophisticated experimental techniques are required to extract a set of physics results from these collision data that is unprecedented in variety. We introduce the ATLAS detector, emphasizing challenges in operations, trigger and data acquisition, and object identification that are overcome through advanced electronics, large-scale distributed computing, and machine-learning techniques.

      POSTER: Probing the Higgs boson with ATLAS
      The 2012 observation of the Higgs boson expanded our understanding of how elementary particles acquire mass, but measurements of its properties are crucial for confirming the validity of the Higgs mechanism and very well may provide evidence for new physics. This poster presents a number of ways in which the DESY ATLAS group has been testing the predictions of the Higgs mechanism, underscoring the challenges involved in the data analyses and how we are learning to overcome them.
      Speakers: Dr Kurt Brendlinger (DESY), Dr Roger Naranjo (DESY)

      POSTER: Precision measurements and extremely rare processes with ATLAS
      This poster presents ATLAS measurements of SM free parameters (the top quark mass and weak mixing angle) as well as recently-observed rare SM processes involving vector boson self-interactions (photon-photon scattering and WW scattering). We highlight how several challenges of these precision analyses, e.g. our lack of knowledge of the proton structure and extremely low signal event rates, are overcome through dedicated supporting measurements and machine-learning techniques.

      POSTER: Dark Matter, Energy, and beyond! with ATLAS
      Less than 5% of the mass of the universe is composed of ordinary matter. An invisible component, called Dark Matter, and a force that repels gravity, called Dark Energy, make up the remainder. The DESY ATLAS group is searching for Dark Matter, Dark Energy, and other Beyond-the-Standard-Model particles produced in the high energy collisions of the LHC. This poster discusses some of our recent efforts toward possible new particles and a deeper understanding of the dark side of the universe.
      Speakers: Katharina Behr (DESY), Dr Othmane Rifki (DESY), Dr Priscilla Pani (DESY)

      POSTER: The ATLAS tracking detector upgrade at DESY
      The high-luminosity phase of the LHC will involve huge numbers of simultaneous collisions. A large section of the upgraded ATLAS silicon strip tracker, which is designed to handle these conditions, will be assembled at DESY. We present the full chain of the silicon strip tracker construction at DESY, including sensor testing, module building, core manufacturing, module-on-core loading, production of electronic interface boards, insertion into end-capstructure, and the global assembly frame.

      Prototyping and Assembly of the CMS Phase-2 Outer Tracker Endcap Support Structure
      For the High-Luminosity LHC, CMS will install a completely new silicon tracker. The DESY groupe participates in this project with buildung one of the tracker endcaps (TEDD). One TEDD is made of five double-disks, each equipped with detector modules on all four faces to ensure a complete coverage. The backbone of the mechanical structure of the TEDDs are highly integrated half-disks, the so-called Dees. A Dee is a carbon fiber sandwich with embedded cooling pipes and module positioning inserts.

      CMS phase-2 TrackerEndcapassemblyat DESY
      For the High-Luminosity LHC, the current CMS tracking detector will be replaced by a new tracker during the shutdown starting in 2024. Pre-production of the new tracker will start in 2020. The CMS group at DESY, along other international institutions, will deliver the end-caps of the new tracker. Specifically our group is committed to fully integrate one of the two end-caps. DESY-CMS physicists and engineers are developing the end-cap assembly concept and designing the corresponding tooling.

      Software for Preparing Future Collider Experiments
      Designing Particle Physics Detector for Future Accelerators, like the International Linear Collider, CLIC or FCC-ee requires sophisticated software tools. These include the detailed description of the detector, the simulation of its electronics signal from particle interactions, as well as complex algorithms for reconstructing the individual particles that have been created in the events. The FLC-software group is leading this effort in close collaboration with international partners.

      Future lepton colliders, like the International Linear Collider (ILC), will complement the potential of the LHC by performing high-precision measurements of the Standard Model of particle physics and searches for new particles. The physics programme of the ILC covers a broad range of aspects, like high-precision measurements of the properties of the Higgs boson and the top quark and tests for beyond the Standard Model physics.

      Measuring light-by-light scattering with the LUXE experiment
      LUXE(Laser Und EuropeanXFEL Experiment) uses collisions of high-energy photons from the electron beam and a high-intensity laser. Quantum electrodynamics predicts the creation of $e^+e^-$ pairs. As the laser intensity increases, so does the field strength, allowing for the first time to probe the so-called critical field. At this high field strength, perturbation theory cannot be applied anymore. In this poster, the planned experimental setup and the expected physics results will be shown.
