Recent studies indicate that the decay width $\Gamma(\pi^0\to\gamma\gamma)$ is strongly reduced in the presence of a uniform external magnetic field. In this work, we study the effect of the magnetic field on the production of neutral pions in photon-photon interactions in ultra-peripheral heavy-ion collisions. In addition, we present the calculation of the production cross section of the...
The LHCb detector, with its forward rapidity coverage, can probe kinematic regions at low Bjorken-x as low as $10^{-6}$. This unique capability, combined with excellent momentum resolution, vertex reconstruction, and particle identification, enables precision measurements at low transverse momentum and forward rapidity.
Studies of associated production of $\Psi(2S)$ and $\Phi$ in diffractive...
The study of charge asymmetries in three-body 𝐵 ± → h h h decays provides a sensitive probe of CP violation in the beauty sector. Using the first data collected during LHCb Run 3, we are performing a preliminary investigation aimed at measuring these asymmetries through fits to the invariant mass distributions of selected candidates. The upgraded detector and higher instantaneous luminosity of...
Rare decays of B mesons, such as B⁰ → K*⁰(892)μ⁺μ⁻, play a crucial role in testing the Standard Model (SM) of particle physics and probing potential signs of New Physics (NP). These flavor-changing neutral current (FCNC) processes are forbidden at tree level in the SM and occur only via higher-order loop diagrams, making them extremely sensitive to virtual contributions from beyond the SM...
In this work, we analyze the scaling properties of Yang-Mills field theory that manifest as self-similarity of n-point functions truncated by the scale evolution. In certain approaches, fractal structures are used in Yang-Mills theories to circumvent computational difficulties, allowing the determination of an analytical expression for the coupling constant, which agrees with the results...
This work consists of a projection study on the efficiency of the PPS detector in the high-luminosity regime through the CEP process $pp\rightarrow p(W^{+}W^{-})p$ with hadronic decay in both W bosons. Simulated samples containing: signal for SM, anomalous coupling $a_0^W = 2\times 10^{-7}$, anomalous coupling $a_C^W = 2\times 10^{-5}$, and with the QCD background for $pp\rightarrow 4J$, were...
The High-Luminosity LHC (HL-LHC) presents challenges due to up to $200$ simultaneous interactions per beam crossing, where around $10\sim15\%$ of the reconstructed vertices are composed of multiple interactions time-separated by about $\sim150~\text{ps}$, which degrades the performance and the accuracy of the event reconstruction. To mitigate this, it is required to employ more precise timing...
The unprecedented proton-proton collision energy and the large data volumes reached by the LHC and the CMS detector with supreme particle detection capabilities provide a unique setting for discovering the particle constituting the dark matter. Since the beginning of the LHC, there were various DM searches within the CMS experiment. With this analysis, we embark on a novel search for...
