We consider a class of Lagrangians in which the kinetic term has a noncanonical form. Among models based on this class of Lagrangians, usually referred to as k-essence, and in the context of cosmology and inflation theory to k-inflation models, we consider in more details a family of Dirac-Born-Infeld (DBI) Lagrangians.
In the last several decades they find a significant room of application...
Jordan algebras were invented in a search of an axiomatic system for quantum mechanics.
They turn out to be extremely effective in describing conformal symmetries via the Tits-Kantor-Koecher construction assigning a light cone to each Euclidean Jordan algebra.
Using the Gunaydin oscillator realization we construct quantum mechanics systems with hidden
conformal symmetry in various...
In this talk we will review the newly developed method for quantization of noncommutative (NC) field theories, the braided BV quantization. We will discuss results for the NC QFT on the Moyal space and then we will generalize these to a spacetime with non-constant noncommutativity, the lambda-Minkowski spacetime. We will show that, in the case of scalar field theory, the NC contribution...
Higher derivatives extensions of MCSP model are considered. The Hamiltonian structure and the equivalence with some first class theories will be investigated, from the point of view of the Hamiltonian path integral quantization.
The analysis of consistent interactions that can be introduced between a collection of BF models and a system of massless scalar fields, done in the context of antifield-antibracket symmetry by deformation to the solution to the classical master equation, exhibits two geometric structures related to the target manifold of the BF scalar fields: i) a Poisson one, due exclusively to BF sector and...
A new approach, PDF2ISR, constructing an initial state parton shower which is fully consistent with the parton densities is applied to Drell-Yan production.
PDF2ISR is implemented inside the Pythia8 event generator and allows a full comparison with measurements.
This new approach is systematically cross checked with predictions using the same parton densities, including Transverse Momentum...

It will provide the necessary tools and research infrastructure that will enable the CMS Albania UT-UPT Group to carry out its duties with high quality and efficiency. The laboratory will offer Albanian...
Random tensor models, seen as quantum field theoretical (QFT) models, are a natural generalization in dimension higher than 2 of the celebrated random matrix models (known, amongst other, to be related to 2D quantum gravity). Moreover, it was discovered by Witten that tensor models are also related to the holographic Sachdev-Ye-Kitaev model.
I this talk I will present an overview of various...
The transition to low-carbon energy systems requires analytical tools that integrate economic interdependencies with the laws of thermodynamics. This study develops a thermodynamically extended Leontief Input-Output (I-O) model, incorporating Environmentally Extended Input-Output Tables (EE-IOTs), to quantify exergy flows, emissions intensities, and entropy generation across Italyโs key...
Based on two recent papers [1]-[2] we discuss the enlarging of the Standard Model - up to six fermion generations and two different Higgs doublets, while keeping the same gauge group $SU(3)_{c}\otimes SU(2)_{L}\otimes U(1)_{Y}$ undergoing the SSB to $SU(3)_{c}\otimes U(1)_{em}$ - in order to have it predicting (i) the quantization of both electric and weak charges; (ii) the muon anomalous...
An important way to characterize the overall features of high-energy nuclear collisions is to analyze the transverse momentum distributions of produced particles. In these collisions, the differences in shape between the positive and negative pion transverse momentum spectra at low pT can be used to study the Coulomb final-state interaction. The charged pions, as the most abundantly produced...
The LHC experiments provide measurements of Standard Model production cross sections with unprecedented precision, which is essential for making new discoveries and exploring potential new physics. These measurements offer crucial input for cutting-edge theoretical model calculations, as well as for the development of new models. This presentation reviews recent Standard Model physics...
Despite its great success, the general theory of relativity is not the final theory of gravity. In addition to other problems, some shortcomings of the standard model of cosmology led to the search for a more general theory of gravity. One of the promising lines of research is the nonlocal theory of gravity. In this talk, I will present a simple nonlocal de Sitter gravity, its several exact...
Two particle correlations have shown the presence of long-range rapidity correlations in small collision systems. Several other measurements provided insight into the unexpected collective behaviour similar to the one exhibited in heavy-ion collisions. These properties can be explained by several models, which consider a microscopic description like PYTHIA 8 and a macroscopic treatment as...
Microlensing is an effective tool for constraining the properties of compact dark matter candidates, such as Primordial Black Holes (PBHs). Standard photometric observations of microlensing events offer valuable insights into the mass and spatial distribution of PBHs. However, degeneracies among lensing parameters often limit the precision of these measurements. A promising approach to...
We present recent measurements of W and Z boson production using the CMS detector at the LHC at CERN. The production mechanisms of these processes are well understood within the Standard Model, and their high-precision measurements help confirm the fundamental principles of particle physics. Moreover, they serve as โstandard candlesโ for probing other processes and for the search for signs of...
The CMS experiment at CERN uses a two-level triggering system to select and store important events for physics. This system is made of the Level-1 (L1) stage, based on custom-designed electronics, and the High Level Trigger (HLT) stage, a sped-up version of the offline software reconstruction running on a computer farm. New trigger algorithms, coupled with advanced technological developments...
We analyze optimal finite-time thermodynamic transformations in black hole spacetimes using geometric control theory. For Schwarzschild and Kerr black holes, we study protocols minimizing entropy production or energy cost under constraints set by thermodynamic metrics. We compare Hessian and Legendre-invariant thermodynamic geometries, focusing on their influence on thermodynamic length and...
We study cosmological inflation with two real scalar fields. We start from one scalar field with the DBI-type Lagrangian, which is of non-canonical form This scalar field can be related to a perfect fluid which describes (dominant) matter in the Universe at a time of interest.
We then extend the model introducing auxiliary real scalar field. The second field does not carry any dynamics,...

Future electron-positron colliders can determine the absolute couplings of the Higgs boson to Standard Model particles in a model-independent manner and obtain a precise measurement of the Higgs bosonโs decay width. Two key ingredients are the determination of the absolute Higgs to Z boson coupling, gHZZ, using the recoil method in the Higgsstrahlung Higgs production channel and the...
