This work presents an analysis proposal for a search for a heavy scalar particle produced in proton-proton elastic collisions at 13 TeV via a Central Exclusive Process (CEP), tagged with the Proton Precision Spectrometer (PPS) and associated with a boson detected in the central region of the Compact Muon Solenoid (CMS) detector. The proposed analysis is done by evaluating the proton mass spectrum

Ultraperipheral collisions at the LHC provide a unique environment to study photonuclear interactions through quasi-real photons generated by the intense electromagnetic fields of relativistic nuclei. Coherent vector-meson photoproduction is a sensitive probe of the structure of nuclei at high energies, and it allows nuclear effects to be studied in the transition region between the perturbative a

Reducing the environmental impact of Resistive Plate Chambers (RPCs) requires alternative gas mixtures that preserve detector performance. This study investigates the timing response of double-gap RPC prototypes equipped with CMS Upgrade iRPC gaps, comparing the standard CMS gas mixture with the reduced-global-warming-potential HFO/CO₂-based mixture ECO2. Test-beam data collected at CERN’s Gam

Ultra-peripheral collisions (UPCs) at the LHC provide a unique laboratory for studying
photon–photon and photon–nucleus interactions, giving access to fundamental aspects of
QED and QCD. In these collisions, the nuclei do not interact hadronically; their intense
electromagnetic fields instead induce photoproduction, with clean signals and low transverse
momenta. The π+π− final state pr

Worldline path integrals have been used for decades as an alternative to Feynman diagrams in QED. However, it was only in 2020–2021 that Ahmadiniaz et al. showed how to extend this formalism to the photon-dressed fermion line. One of the most attractive features of this approach is that it completely avoids the appearance of long products of Dirac matrices. In this work, we apply the formalism t

Measurements of hard-process production as a function of charged-particle multiplicity in small systems require a careful control of pileup, since additional interactions modify the multiplicity observable and bias the event classes.

We investigate the effects of compactified extra spatial dimensions on the anomalous chromomagnetic dipole moment (CMDM) of the top quark within the Universal Extra Dimensions (UED) model.

We study dynamical mass generation in a strongly coupled abelian gauge theory when the differential structure of the gap equation is promoted to non-integer order. The starting point is the linearized rainbow Schwinger--Dyson equation, whose integer-order form is an Euler equation.

The context of this work is provided by a variant of the seesaw mechanism in which the light neutrino masses $\nu_j$ are assumed to vanish at tree level and are instead generated through radiative corrections to the neutrino self-energy. Since the analysis is already carried out exclusively in the Feynman–’t Hooft gauge, it is necessary to verify that the induced masses are independent of the

The standard type-I seesaw can also be regarded as a low-scale seesaw by using the freedom of the Casas-Ibarra parameterization. In this framework, radiative corrections to the neutrino mass matrix can dominate over the tree-level contribution. We show that a naive use of the Casas-Ibarra parametrization in the presence of 1-loop corrections leads to incorrect predictions for the neutrino oscillat

The Standard Model (SM) provides an incomplete description of elementary particles and their interactions, therefore an extension or modification is necessary. There are many proposed extensions with added particles to the SM to complement its shortcomings, but so far none of them have been directly detected.

Inclusive hadronic tau decays, $\tau^- \to \text{hadrons} + \nu_\tau$, are well described by QCD and are a valuable source of information about the theory and its fundamental parameters, such as the strong coupling, $\alpha_s$.
