About
My name is Marko Stamenkovic and I am 25 years old. I recently achieved my Master of Science in High Energy Physics at the EPFL within the LPHE group. During my studies, I had the opportunity to work on various particle physics projects. My Master thesis was focused on the search for new physics in rare charm decays. The dataset I analysed was collected by the LHCb experiment in 2016 at CERN. High energy physics is a field where a strong theoretical background mixes up with the statistical realization of the world. Analysis is enabled only through an extraordinary technological and computational effort. For these reasons, I decided to pursue my adventure with a PhD and I had the chance to be accepted in the ATLAS group at Nikhef, Amsterdam, Netherlands. My work will be centered around the Higgs boson and its decay into heavy flavours, especially in the charm sector (H->cc).
The first principle is that you must not fool yourself - and you are the easiest person to fool.

Compressive sensing based on optical coding - Optical realization of the Radon transform
Abstract
In this work we analyze the properties and specificities of the dynamcial, electrically addressed technology of spatial light modulators (SLM). We simulate the lens aberration correcting property in order to compare different devices (Holoeye) and conclude that the GAEA (4094x2464) achieves the best results. We then analyze the optical realization of the Radon transform and its feasibility using a SLM. We propose a novel generalizable implementation of the optical realization of the Radon transform as well as its inverse, we suggest a joint transform correlator setup to realize it and test the image reconstruction based on a small number of projections via compressive sensing methods. We conclude that the results obtained through the optical realization of the Radon transform are similar to some state of the art research on sparse view image reconstruction. In order to demonstrate the applicability of a SLM, we propose two experiments: an alternative proof of the optical Radon transform based on a 4f-correlator and a compressive sensing system known as the double random phase encoding.
Searching for new physics in c->u transitions
Abstract
Rare decays are processes suppressed in the Standard Model which happen only at loop level. As new particles could contribute in the loops at the same level as the Standard Model, these decays are very sensitive to new physics. In particular, we consider the rare decay of Lambda-c baryon into a proton and two muons, wich is a c->ull flavour changing neutral current forbidden at a tree level in the Standard Model. A search for this decay is performed with data collected by the LHCb in 2016, at a center of mass energy of 13 TeV. Two strategies are investigated: promptly produced Lambda-c candidates or coming from the semi-leptonic decay of Lambda-b into a Lambda-c, a muon and a neutrino. Two normalisation channels are also investigated: the Lambda-c+ into a proton, kaon and pion or Lambda-c+ into a proton and a phi-meson.
Interests
My interests lie in the theoretical, experimental and computational aspects of high energy physics.
For the upcoming years, I would like to deepen my knowledge of the Standard Model through Quantum Field Theories. I would also like to explore the hardware aspect of experimental physics and the computational techniques behind particles physics, sustained by statistical and machine learning techniques.
Location
My current location is Lausanne, Switzerland.
