Many early universe theories predict the creation of Primordial Black Holes (PBHs) that could have sufficient mass to be expiring today with a final burst of Hawking radiation. A Black Hole (BH) has a Hawking temperature inversely proportional to its mass. Hence, a sufficiently small BH will quasi-thermally radiate particles at an ever-increasing rate as it evaporates and raises its...
The COmpact Network of Detectors with Orbital Range (CONDOR) Observatory is a future cosmic ray observatory to be constructed at an altitude of 5300 m a.s.l. in the Atacama Desert, making it the highest detector array in the world. CONDOR observatory aims to detect cosmic rays with energies starting at ~100 GeV scale, a range crucial for bridging the gap between satellite and ground-based...
Among the $B$ mesons, the $B_c$ meson is unique as it is the only one composed of two different heavy flavors, $b$ and $c$, making its production and detection more challenging than other $b$-flavored mesons. This results in significant uncertainties in its dynamic properties. Consequently, rather than reporting its differential production cross-section, the LHCb collaboration [1] provides the...
The CONDOR (COmpact Network of Detectors with Orbital Range) project aims to establish the highest-altitude observatory for cosmic rays at the Atacama Astronomical Park in northern Chile. Positioned at 5.300 meters, CONDOR will provide unique sensitivity to low-energy cosmic ray (CR) particles, particularly from ~100 GeV, contributing to our understanding of cosmic rays and their interactions...
We study light neutralinos ($\tilde \chi_1^0$) with masses of the order of the GeV scale in the context of R-parity-violating (RPV) supersymmetry. For such masses, the neutralinos can become long-lived particles and decay with a macroscopic (order cm) displacement inside LHC detectors. Complementing previous works, we focus on their production through a pair of sleptons ($\tilde e_{L}$) with...
The High-Luminosity Large Hadron Collider (HL-LHC) will demand highly efficient and fast data processing systems to handle unprecedented event rates. In this study, we present a novel approach to real-time classification of Higgs boson production mechanisms—focusing on gluon-gluon fusion (ggF) and vector boson fusion (VBF)—using machine learning (ML) models optimized for deployment on...
We evaluate the polarised Bjorken sum rule (BSR) $\overline{\Gamma}^{p-n}_1(Q^2)$ with truncated Operator Product Expansion (OPE) up to the $D=4$ term [1]. Due to the knowledge of the renormalon structure of the BSR, the leading-twist term of dimension $D=0$ is evaluated using a recently developed renormalon-based resummation [2], in this case with two variants of holomorphic QCD couplings...
