Location & approach

By car

The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.

By bus and train

The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offer an interactive route network map.

The H-Bahn

One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.

By plane

From Dortmund Airport, it takes just over 20 minutes to get to Dortmund Central Station by AirportExpress and from there to the university by S-Bahn. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.

Particle colloquium: New multiparticle production variables: bridging the gap between air-shower observables and accelerator measurements

Start: 04/24/2025, 4:00 PM Location: CP-03-123

Miguel Martins will present the topic "Model-Independent phase correction in D → KS π+ π− decays for the precise measurement of CKM angle γ in B± → D K± transitions" on April 24.

Ultra-high-energy cosmic rays (UHECRs) interact with atmospheric nuclei at centre-of-mass energies reaching hundreds of TeV, initiating cascades of secondary particles known as Extensive Air Showers (EAS). These interactions offer a unique window into hadronic particle production in regions of phase space beyond the reach of current particle accelerators. This seminar focuses on two key observables of EAS: the atmospheric depth of the shower maximum (Xmax) and the number of muons at ground level (Nμ). For proton-induced EAS, a probabilistic model is developed to connect these observables with production variables built from the energy spectra of secondary hadrons of the initial UHECR-air interaction. Crucially, this connection enables the probing of hadronic interactions using air-shower data, independently of the hadronic interaction model. Since collider experiments can access similar secondary spectra, our framework bridges high-energy particle physics and astroparticle physics in a unified framework.
