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.

Plan of site & interactive map

The facilities of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".

Measurements of CP violation in decays of beauty mesons to two charmed mesons at the LHCb experiment

In this thesis, two measurements of CP violation in the B→DD system are presented. Both analyses explore proton-proton collision data corresponding to an integrated luminosity of 6 fb-1 collected by the LHCb experiment at a centre-of-mass energy of 13 TeV.

The flavour-tagged decay-time-dependent analysis of about 5700 B0→D+D- signal candidates yields the CP observables

S_D+D- = -0.552 ± 0.100 (stat) ± 0.010 (syst),
C_D+D- = 0.128 ± 0.103 (stat) ± 0.010 (syst).

In the second measurement, approximately 13000 Bs0→Ds+Ds- signal candidates are selected, and the CP observables are determined to be

ϕsDs+Ds- = -0.086 ± 0.106 (stat) ± 0.028 (syst) rad,
|λDs+Ds-| = 1.145 ± 0.126 (stat) ± 0.031 (syst).

These results represent the most precise measurements of CP violation in their respective channels to date and are consistent with Standard Model predictions. For the first time, CP symmetry in B0→D+D- decays is excluded by a single measurement with a significance of more than six standard deviations.
