We draw attention to the role the unphysical phases play in the definition of a neutrino texture, and apply this to two textures: one defined by a vanishing whole trace, and one defined by one-equality and one-antiequality.
This talk introduces a modular-symmetric approach to flavor, motivated by the geometry of extra dimensions. I focus on the modular A4 framework with three moduli, assigned separately to the lepton and quark sectors. At their fixed points, each modulus exhibits a residual symmetry that shapes the corresponding mass and mixing patterns.
The Transformer network, originally introduced for online language translation, has recently achieved remarkable success, particularly with the emergence of the GPT family. In this talk, I will explore how Transformer architectures can be adapted for analyses in particle colliders. At the core of Transformer models lies the attention mechanism. I will review various types of attention...
We probe the anomalous quartic gauge coupling via $WW\gamma$ using Machine Learning transformer algorithms in SMEFT, and improve constraints on the effective field theory parameters.
We present recent advancements in the 3+1 formalism within two reformulations of general relativity: the teleparallel equivalent, and the symmetric teleparallel equivalents of general relativity. Both theories are based on the torsion and nonmetricity of a flat linear connection, respectively, and their Lagrangians are expressed in terms of the torsion scalar T and nonmetricity scalar Q. These...
Taub-NUT spaces are one of the less understood spaces in General Relativity. Here we introduce consistent thermodynamics for these spaces, i.e., thermal quantities satisfy the first law, Gibbs-Duhem and Smarr's relations. Furthermore, we uncover the rich phase structures of these spacetimes for different horizon geometries, which could be spherical, flat, or hyperbolic. We work in extended...
For decades, the Standard Model has provided an excellent explanation for many phenomenological observations; however, several mysteries remain, such as neutrino oscillations and the origin of neutrino mass. Additionally, there are significant tensions with experimental data, including the $7\sigma$ deviation in the W-boson mass reported by the CDF II experiment and the excess of electron-like...
Finsler gravity is a modern extension of Einstein's General Relativity, using Finsler geometry (which generalizes Riemannian geometry) to describe spacetime, allowing for direction-dependent physics, potentially explaining phenomena like dark energy or dark matter, and offering new perspectives on cosmology by studying non-Riemannian "Finsler spacetimes" that still recover Einstein's theory in...
The dynamics and the gravitational field of kinetic gases are usually described by the Einstein-Vlasov/Boltzmann equations. The evolution of the gas on phase space is encoded in the 1-particle distribution function (1PDF), while the Einstein equations determine the gravitational field of the kinetic gas from an energy momentum tensor that is obtained by averaging the 1PDF over all physical gas...
We propose a modification to the standard hybrid inflation model, that
connects a successful hybrid inflation scenario to the standard model higgs sector, via
the electroweak vacuum stability. The proposed model results in an effective inflation
potential of a hilltop-type, with both the trans-Planckian and sub-Planckian inflation
regimes are consistent with the recent Planck/BICEP...
The nature of Dark Energy remains one of the most profound mysteries in modern cosmology, acting as the primary driver behind the late-time accelerated expansion of the universe. This talk explores the current landscape of dark energy research in light of the latest Baryon Acoustic Oscillation (BAO) observations from premier surveys such as the Dark Energy Spectroscopic Instrument (DESI). We...
Adopting Bazanski approach, two new classes of path equations are derived in Einstein non-symmetric geometry. The first class is the path equations of a test particle moving in a gravitational field, while the second class represents path equations of charged particles. The path equations of charged particles give rise to Lorentz force. Moreover, these path equations may represent an...
Higher-dimensional gravity is not just an extension of Einstein’s theory, and the physics of higher-dimensional black holes is not only richer, but also different from that in 4-dimensions.
In this work, we investigate the extended thermodynamics of charged, rotating black holes with equal angular momenta in five-dimensional anti-de Sitter spacetime within the framework of Chern-Simons...
Extended Palatini gravity is the metric-affine gravity theory characterized by zero torsion, nonzero metricity and a quadratic of the antisymmetric Ricci curvature. It reduces dynamically to general relativity plus a geometric Proca field. In this work, we study imprints of the geometric Proca field on the gravitational waves. Our results show that the geometric Proca leaves significant...
We discuss a new source of gravitational waves (GWs) from first-order phase transitions arising from particle production from the walls of bubble walls, which inevitably modifies the standard GW spectrum produced from bubble walls collisions hitherto known. The new characteristic feature of the GW spectral shape entails a change of slope in frequency, which could be detected at GW detectors...
Gravitational waves offer a powerful probe of the early universe, providing insights into its dynamics and fundamental physics. This talk will explore the stochastic gravitational wave background (SGWB) and its potential origins, including signals detected in the NANOGrav 15-year dataset. I will discuss how hybrid inflation can generate topological defects, such as cosmic strings, and...
Future gravitational-wave observatories will operate in a regime of unprecedented sensitivity, long-duration signals, and complex environmental noise. In this talk, I will discuss recent developments in applying machine learning to gravitational-wave data analysis, with a focus on deep-learning models for signal detection, the separation and reconstruction of overlapping long-duration signals,...
Accurate background modeling and signal extraction are central challenges in modern neutrino, cosmology, and astroparticle physics experiments, which operate on large and complex datasets. In this talk, I present recent applications of artificial intelligence to background estimation in high-energy physics, with a focus on machine-learning–based methods developed within the CMS experiment....
Abstract: We examine the angular distribution of both low and high-mass dimuon pairs using the open data from CMS, and with simulated electron-positron collisions from the proposed International Linear Collider (ILC). This collider operates at a center-of-mass energy of 500 GeV and is designed with an integrated luminosity of 4 ab(^{-1}). Our main focus revolves around the...
The current CMS muon system employs a combination of detector technologies, each optimized for specific regions. Drift Tubes (DT) and Resistive Plate Chambers (RPC) are deployed in the barrel, while the endcap utilize cathode strip chambers (CSC) and RPC. To address the anticipated higher background rates in the endcap, new detector stations will be installed. These stations will utilize...
We study the collider phenomenology of the $B$-$L$ extension of the Standard Model (BLSM), focusing on the production and decay of a heavy neutral gauge boson (( Z' )) at the Large Hadron Collider (LHC). In this framework, the ( Z' ) can decay into pairs of heavy right-handed neutrinos (( \nu_R )), which subsequently decay into charged leptons and ( W ) bosons. These processes give...
