86. Dark Matter at the LHC

James Frost (University of Oxford)

6/5/25, 10:00 AM

Accelerator Searches for DM

Invited Talk

The astrophysical evidence for dark matter provides compelling argument for the existence of physics beyond the Standard Model. Collider experiments such as ATLAS offer the ability to search for dark matter at high energy scales and characterise its interactions, and provide complementarity probes to direct and indirect dark matter detection searches and dedicated low mass dark matter...

57. Searches for new physics using unconventional signatures or unconventional workflows using the ATLAS detector

Viktoriia Lysenko (Czech Technical University, Prague)

Accelerator Searches for DM

Contributed Talk

Many theories beyond the Standard Model (SM) have been proposed to address several of the SM shortcomings. Some of these beyond-the-SM extensions predict new particles or interactions directly accessible at the LHC, but which would leave unconventional signatures in the ATLAS detector. These unconventional signatures require special techniques and reconstruction algorithms to be developed,...

82. Searches for dark sector signatures from CMS (emerging jets, semivisible jets, SUEP)

Cesare Cazzaniga (ETH Zürich)

6/5/25, 10:55 AM

Accelerator Searches for DM

Contributed Talk

Among the intriguing scenarios of new physics that provide explanation to several shortcomings of the Standard Model (SM), hidden valley scenarios include a Dark Sector that extends the SM with a non-Abelian gauge group, similar to quantum chromodynamics with new matter and gauge fields analogous to the SM quark and gluon fields. This may result in a rich phenomenology which we can access...

40. Constraining Dark Photon Kinetic Mixing in Heavy-Ion Collisions from SIS to LHC energies

Adrian William Romero Jorge (Frankfurt Institute for Advanced Studies/Institut für Theoretische Physik, Johann Wolfgang Goethe-University/HFHF)

Accelerator Searches for DM

Poster + Lightning Talk

Vector $U$-bosons, commonly known as 'dark photons', are hypothesized mediators of dark matter interactions. In this study, we establish a methodology to set theoretical constraints on the upper limit of the kinetic mixing parameter $\varepsilon^2(M_U)$ by analyzing dilepton spectra from heavy-ion collisions spanning SIS to LHC energies. Our approach relies on the microscopic...
