Research

Our research is conducted in the fields of particle physics and astroparticle physics.

Our projects

  • Higgs physics beyond the Standard Model with the ATLAS  experiment at CERN's Large Hadron Collider
  • Signatures of the photosphere in GRBs
  • GRB jet properties, particle acceleration, emission mechanisms
  • Disk jet connection in AGNs
  • Multiwavelength studies of blazars

Particle physics

Particle physics is a branch of physics that studies the nature of the particles that constitute matter and radiation. Although the word particle can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), particle physics usually investigates the irreducibly smallest detectable particles and the fundamental interactions necessary to explain their behaviour.

The research of particle physics group here at KTH is based on the frontline of hadron collider experiments. The main scientific goals are to search for the Higgs boson and to probe for physics beyond the standard model, where the search for supersymmetry is a key element. One fundamental question is if the lightest supersymmetric particle constitutes the bulk of the dark matter. The KTH group has since 1990 taken its share in the development and later the construction of the ATLAS liquid argon electromagnetic calorimeter. ATLAS is one of the large experiments at the CERN Large Hadron Collider. KTH has shared the responsibility for the construction, assembly and testing of the ATLAS presampler with a research group from Grenoble. This device, mounted inside the barrel liquid argon cryostat compensates for energy losses in front of the electromagnetic accordion type calorimeter. The group is also involved in ATLAS heavy quark studies as a probe of QCD.

Astroparticle physics

Astroparticle physics is a branch of particle physics that studies elementary particles of astronomical origin and their relation to astrophysics and cosmology. It is a relatively new field of research emerging at the intersection of particle physics, astronomy, astrophysics, detector physics, relativity, solid state physics, and cosmology.
Currently we are doing research within :

Gamma-ray bursts and AGNs

  • Signatures of the photosphere in GRBs
  • GRB jet properties, particle acceleration, emission mechanisms
  • Disk jet connection in AGNs
  • Multiwavelength studies of blazars
     

Instrumentation and development of new space missions

KTH Space Center

KTH Space Center coordinates and promotes space-related activity at several KTH departments, with an overarching objective of establishing KTH as a "Space University" and a hub for Swedish space research and technology.

Oskar Klein Centre

We are a part of the Oskar Klein Centre for Cosmoparticle Physics where researchers and students enjoy a large palette of supporting activities like weekly OKC Colloquia, biweekly Working Group meetings, OKC-day gatherings every term, and monthly cross-disciplinary science pubs. The OKC carries out a number of popular science outreach activities in order to share our operations with the public.
