Anti-nuclei studies at ALICE
2020-05-28 – Since anti-matter could be interpreted as a dark matter annihilation signal, satellite and balloon experiments are currently hunting for dark matter particles near Earth. But anti-matter could also be produced by interactions of high-energy cosmic rays with the interstellar medium. To better understand the production mechanism and the annihilation of anti-matter, the ALICE collaboration has conducted a comprehensive study of the yield of anti-matter resulting from proton-proton collisions and evaluated for the first time the cross section of anti-deuteron at low energies.
Temperatures of 800 billion degrees in the cosmic kitchen
2019-08-23 – It is among the most spectacular events in the universe: a merger of neutron stars. An international team of researchers with strong representation from the Technical University of Munich (TUM) has completed the first laboratory measurements of thermal electromagnetic radiation arising in such collisions. The resulting data enabled them to calculate the prevailing temperature when such stars merge.
International conference on particle detectors
2018-06-18 – From 18 to 22 June, international experts on gaseous ionizing particle detectors gather at TUM in Garching for the RD51 Collaboration Meeting. Prof. Laura Fabbietti and Dr. Piotr Gasik from the Physics Department organize the conference at TUM’s Institute for Advanced Study. About 70 leading experts from 15 countries around the globe join the meeting.
Breakthrough in Multi-Messenger Astronomy
2017-10-16 – Live at the Physics Department: Announcement of groundbreaking observations of an astronomical phenomenon that has never been witnessed before.
Prestigious ERC grants for research projects in physics
2017-09-05 – Two young scientists at TUM’s physics department will receive Starting Grants from the European Research Council (ERC). In addition a full professor is awarded a Proof of Concept Grant. Each of the three research fields at the department – Biophysics, Condensed Matter Physics and Nuclear, Particle and Astrophysics – has recieved one of the prestigious awards.
New ALICE results show novel phenomena in proton collisions
2017-05-08 – In a paper published in Nature Physics, the ALICE collaboration at CERN reports that proton collisions sometimes present similar patterns to those observed in the collisions of heavy nuclei. This behaviour was spotted through observation of so-called strange hadrons in certain proton collisions in which a large number of particles are created.
Precise comparison of light nuclei and antinuclei
2015-09-07 – Our existence is still a great mystery in theoretical physics. Why did anti-matter disappear almost completely from our universe, whereas matter did not? Scientists are attempting to solve this mystery at the particle accelerator of the major European research institute at CERN. The ALICE collaboration has now published the most precise measurement of the properties of light atomic nuclei and anti-nuclei ever made in the journal “Nature Physics”. Scientists from the physics department at Technical University of Munich (TUM) are working on new detectors for the ALICE experiment which will improve the precision of future measurements.
