The ePIC detector is specifically designed to address the entire physics program
at the Electron-Ion Collider (EIC). It consists of several sub-detectors, each tailored
to address specific physics channels. One of the key sub-systems of ePIC is
the dual-radiator Ring Imaging Cherenkov (dRICH) detector, which is a highmomentum
particle-identification system located in the hadronic end-cap....

The present work is about a new method to sample the quantum fluctuations of relativistic fields by means of a pseudo-Hamiltonian dynamics in an enlarge space of variables. The proposed approach promotes the fictitious time of Parisi-Wu stochastic quantisation to a true physical parameter controlling a deterministic dynamics. The sampling of quantum fluctuations is guaranteed by the presence...
The rare decays of the $B_c$ meson induced by the flavour changing neutral current $c \to u$ transition are strongly suppressed by the Glashow-Iliopoulos-Maiani mechanism in SM. Therefore, they exhibit sensitivity to new physics effects, as long as the impacts from long-distance contributions can be controlled. The difficulty is to get rid of these hadronic effects. I will present a study of...
Constituting the largest fraction of all multiquark states observed by experiment, tetraquark mesons carrying overall quark flavour quantum numbers identical to those of conventional quark–antiquark mesons necessitate their particularly careful phenomenological treatment. A collection of (more or less recent) insights specific to the latter subset of exotic hadrons promises to enable...
This poster examines the interplay between the conformal trace anomaly and the gravitational form factor of the pion within the framework of Quantum Chromodynamics (QCD). By focusing on the 1-loop calculation, we investigate the non-abelian TJJ three-point function and TJJJ four-point function. These calculations provide information on the contributions arising from the conformal trace anomaly...
The ALICE Collaboration is proposing a completely new apparatus, ALICE 3, for the LHC Runs 5 and 6. The detector comprises a large pixel-based tracking system covering eight units of pseudorapidity, complemented by various particle identification systems including silicon time-of-flight layers, a ring-imaging Cherenkov detector, a muon identification system, an electromagnetic calorimeter and...
This research investigates the consequences of first-order phase transitions in the early Universe, specifically in extensions of the Standard Model that include dark matter. The study focuses on a scenario based on a dark SU(2) group and provides a case study for assessing the sensitivity of future gravitational wave signals from phase transitions in connection with the phenomenology of dark...
In this presentation, we will discuss the QCD phase diagram at finite temperature and finite baryon chemical potential using a holographic AdS/QCD model. We study backreacted bulk gravity solutions with appropriate boundary conditions representing strongly interacting nuclear matter, deconfined quarks, and various possible condensates in a spectrum of chemical potentials and temperatures.
Soft function exponentiates in terms of the Soft anomalous dimension; the Feynman diagrams contributing to it are called Cwebs. The colour and kinematics of a Cweb mix via a web mixing matrix -- calculation of web mixing matrices at higher loop orders is a nontrivial task using the replica trick, and a long-awaited aim is to construct these matrices, bypassing the replica trick.
Our works...
Studying electromagnetic form factors is crucial to understand the internal structure of hadrons, which provides information about the charge distributions and magnetic moments of hadrons. However, quantum chromodynamics cannot be used to compute these non-perturbative quantities.
In this talk, we present a study on the meson spectra, decay constants, electromagnetic form factors, and charge...
We review the Hadronic Light-by-Light (HLbL) contribution to the muon anomalous magnetic moment. Upcoming measurements will reduce the experimental uncertainty of this precision observable by a factor of four, thus breaking the current balance with the theoretical prediction. A necessary step to restore it is to decrease the HLbL contribution error, which implies a study of the high-energy...
We investigate the renormalization-group scale and scheme dependence of the $H \rightarrow gg$ decay rate at the order N$^4$LO in the renormalization-group summed perturbative theory, which employs the summation of all renormalization-group accessible logarithms including the leading and subsequent four sub-leading logarithmic contributions to the full perturbative series expansion. ...
