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: Probing the Standard Model using measurements of semi-leptonic decays at Belle and Belle II

Summer semester 2024 Location: CP-03-123

On 24.06 Dr. Frank Meier will speak on the topic "Probing the Standard Model using measurements of semi-leptonic decays at Belle and Belle II".

Abstract:
The Standard Model of particle physics (SM) has been completed with the observation of the Higgs boson in 2012. However, many questions like the explanation for the large matter-antimatter asymmetry observed in today's universe or the hierarchy problem remain unanswered. The Belle II experiment at the SuperKEKB electron-positron collider at KEK aims at providing new insights into these and other questions by performing indirect searches for physics beyond the SM in the electro-weak sector. The kinematic constraints from the well-defined initial state are especially advantageous in semi-leptonic decays with missing energy.
For some time, a persistent deviation between the standard model expectation and the experimental results is observed for the ratio R(D(*)) between the branching fractions B(B → D(*) τ+ντ) and B(B → D(*) l+νl) (l = e, µ), which hints at a potential violation of lepton flavor universality. One of the leading uncertainties in the measurements is the limited understanding of semi-leptonic decays involving orbitally excited charmed mesons (D**). In my presentation I will show current studies and the latest results by Belle and Belle II on R(D(*)) and B → D** l+νl decays.
