I'm a postdoc at IBS Center for Theoretical Physics of the Universe (Particle Theory and Cosmology Group), where I work on BSM phenomenology focused on light, typically sub-GeV, new particles related to intensity frontier searches, dark matter, and cosmology. I obtained my PhD in 2022, where I worked with Prof. Leszek Roszkowski and Dr. Sebastian Trojanowski. Research highlights from my PhD studies can be found in PhD Projects page. Before, I did my B.Sc. and M.Sc., supervised by Prof. Janusz Rosiek and Prof. Stefan Pokorski in University of Warsaw, where this webpage is hosted.

Fig. 1: Color-filled contours correspond to the contribution of secondary production to the sensitivities of FASER, SHiP and MATHUSLA detectors. The reach is extended to short lifetime regime, covering both the (g-2)μ and the relic density areas.
Intensity frontier searches for long lived particles
Large Hadron Collider discovered the Higgs boson in 2012 by making use of detectors looking for heavy, TeV-scale particles which are produced with weak-scale strength interactions. On the other hand, most of the states produced in proton proton collisions actually travel parallel to the beamline and escape large, but short detectors, like ATLAS and CMS. To take advantage of such "wasted” flux, several essentially zero-background experiments has been proposed like FASER, MATHUSLA, CODEX-b, MoeDAL, among others. Part of their physics program is dedicated to looking for new, light long lived particles. We studied secondary production of such state taking place by scattering with material located right in front of the detector [2]. We showed that such mechanism can significantly extend the sensitivity of the aforementioned detectors to shorter lifetime regime.
Non-standard neutrino interactions
We extended the secondary production mechanism to models with extended neutrino sector [3]. We studied dark neutrino portal and neutrino magnetic portal (shown in Fig. 4), among others, which are motivated by, e.g., various direct detection and neutrino experiments anomalies and neutrino mass generation. Once again, we found significant extension of parameter space coverage thanks to the secondary production. In addition to the displaced vertex signature (which is responsible for the reach shown in Fig. 1) we also studied scattering signatures taking place in the emulsion cloud chamber (ECC) detector at FASER2nu.
Fig. 2: FASER2nu sensitivity to neutrino magnetic portal due to secondary production. Green line at the bottom corresponds to displaced vertex signature, yellow line denotes scattering with electrons at the ECC while red bottom line represents secondary production followed by decay at the ECC. FASER2nu is the proposed extension to already working FASER experiment.
