In the life of every scientist there is a moment when ey realizes: "If I really want to continue to do science, I need to get my own financing". This talk is about my struggle in writing my very first major grant proposal. I will tell you how I arrived at this idea, how I decided on the topic, what the full paperwork looks like and what one should not forget. Disclaimer: At this very moment,...

While quantum chromodynamics (QCD) allows the calculation of processes governed by the strong interraction, trying to describe more complex objects like nucleons requires us to simplify the theory with a model. One such simplification is the dipole model accompanied by the Balitsky-Kovchegov (BK) equation. By numerically solving the BK equation, we can calculate the scattering amplitude and...

The study of incoherent production of a vector meson in diffractive processes provides information about the inner composition of the target hadron at the partonic level. The incoherent cross section is sensitivite to fluctuations in the configuration of the color field of the target. The energy-dependent hotspot model, based on the color dipole approach, incorporates subnucleon degrees of...

A solution of the target-rapidity Balitsky-Kovchegov (BK) equation is presented considering, for the first time, the complete impact-parameter dependence, i.e. including the orientation of the dipole with respect to the impact-parameter vector. To address the non-local behaviour introduced in the target-rapidity formulation of the BK equation, three different prescriptions are considered to...

The Balitsky-Kovchegov evolution equation tells us much about the gluonic structure of hadronic targets in accelerator experiments. As its leading order form has been around for decades with great successes in high-energy phenomenology, the next-to-leading order version (yielding a more accurate description of the scattering process) proves to be a tough nut to crack. In this talk, we will crack it.

Dark matter is an astrophysical phenomenon of our time. Apart from observations of its effects on objects in the Universe, it has still not been detected directly on Earth. Its detection is a matter of current research, with limits to the possibility of simultaneous detection assumed based on its velocity distribution. This thesis discusses methods for accelerating dark matter. In particular,...

Solving problems in contemporary physics often comes hand in hand with the need for accurate numerical integration. With every additional dimension that needs to be integrated over, this problem becomes increasingly more difficult and at some point unsolvable. One possible way to tackle this issue comes with Monte Carlo Importance Sampling integration. I will introduce this method along with...

The Muon Forward Tracker (MFT) is a silicon pixel detector that was installed as part of the ALICE upgrades in preparation for Run3. This talk presents the current status of MFT together with an overview of its performance during a crucial Pb-Pb data-taking period in 2023. Furthermore, the talk shows several upgrades that were done to various MFT subsystems in order to improve the detector...

The ALICE collaboration is proposing a full detector upgrade to be installed during the Long Shutdown 4. The subsystem discussed in this talk is the Muon Identifier (MID), which will focus on the J/psi at rest reconstruction. This set the requirement for identification of the muons at 1.5 GeV/c transverse momenta with this detector. The current progress of the scintillator working group and...

The ProtoDUNE experiment at CERN is crucial in advancing our understanding of neutrino physics and particle detection technologies. This talk will explore the innovative processes used in ProtoDUNE, with a focus on transforming waveform data into charge histograms. By converting complex waveform signals into meaningful charge distributions, we gain critical insights into particle interactions...

ALICE needs to upgrade current FDD (Forward Diffractive Detector) for Run 4. There are several problems that require to be eliminated for run 4 but mainly my thesis deals with shortening time response signal. In my presentation I will discuss basics of FDD, current problems with it, solutions and what to expect from my work in months to come.

The wave function entering the amplitude for vector meson production includes the part, where the dipole collapses into a vector meson. This process cannot be computed analytically, because of its non-perturbative character, so there are different models to describe this process. These models

This talk presents one of the first results on the measurements of the J/psi vector meson in the central barrel of ALICE. The presented analysis was done on 30 runs of the 2023 Pb-Pb data-taking period with reconstructed apass2. The results show a need for stricter cut setting and cut analysis for skimmed datasets. Furthermore, it contains one of the first results on the measurements of J/psi...
