Probing proton structure with correlations in ultraperipheral collisions

Barbara Linek, Agnieszka Łuszczak, Marta Łuszczak +3

We study the exclusive diffractive photoproduction in ultraperipheral collisions. The formalism makes use of off-diagonal generalizations of the unintegrated gluon…

Exploring mixed lepton-quark interactions in non-resonant leptoquark production at the LHC

João Gonçalves, António P. Morais, António Onofre +1

Searches for new physics (NP) at particle colliders typically involve multivariate analysis of kinematic distributions of final state particles produced in a decay of a hypothetica…

Glueball dark matter, precisely

Pierluca Carenza, Tassia Ferreira, Roman Pasechnik +1

We delve deeper into the potential composition of dark matter as stable scalar glueballs from a confining dark gauge theory, focusing on . To predict the relic…

Exploring the viability of pseudo Nambu-Goldstone boson as ultralight dark matter in a mass range relevant for strong gravity applications

António P. Morais, Vinícius Oliveira, António Onofre +2

We study a simple extension of the Standard Model featuring a dark sector with an ultralight pseudo Nambu-Goldstone boson as dark matter candidate. We focus on the mass range $\mat…

Gravitational echoes of lepton number symmetry breaking with light and ultralight Majorons

Andrea Addazi, Antonino Marcianò, António P. Morais +3

We formulate a version of the low-scale Majoron model equipped with an inverse seesaw mechanism featuring lepton-number preserving dimension-6 operators in the scalar potential. Co…

Fractal derivatives, fractional derivatives and -deformed calculus

Airton Deppman, Eugenio Megias, Roman Pasechnik

This work presents an analysis of fractional derivatives and fractal derivatives, discussing their differences and similarities. The fractal derivative is closely connected to Haus…
