A new look at the states from a molecular perspective
Albert Feijoo, Wen-Fei Wang, Chu-Wen Xiao +4
We have a look at the states generated from the interaction of coupled channels. We consider the blocks of pseudoscalar-baryon $({\frac12}^+…
and its interactions with a kaon: open charm states with strangeness
Brenda B. Malabarba, K. P. Khemchandani, A. Martinez Torres +1
In this work we present an attempt to describe the found by the LHCb collaboration, in the experimental data on the invariant mass spectrum of , as a three-mes…
Long-lived heavy neutral leptons from mesons in effective field theory
Rebeca Beltrán, Giovanna Cottin, Juan Carlos Helo +3
In the framework of the low-energy effective field theory of the Standard Model extended with heavy neutral leptons (HNLs), we calculate the production rates of HNLs from meson dec…
Schwinger mechanism for gluons from lattice QCD
A. C. Aguilar, F. De Soto, M. N. Ferreira +4
Continuum and lattice analyses have revealed the existence of a mass-scale in the gluon two-point Schwinger function. It has long been conjectured that this expresses the action of…
Non-unitary three-neutrino mixing in the early Universe
Stefano Gariazzo, Pablo Martínez-Miravé, Olga Mena +2
Deviations from unitarity in the three-neutrino mixing canonical picture are expected in many physics scenarios beyond the Standard Model. The mixing of new heavy neutral leptons w…
Exotic states with triple charm
M. Bayar, A. Martinez Torres, K. P. Khemchandani +2
In this work we investigate the possibility of the formation of states from the dynamics involved in the system by considering that two 's generate a bou…
The as a threshold effect from the interaction of the , channels
R. Molina, E. Oset
We look at the mass distribution of the in the decay, where a peak has been observed in the region of the , thresholds.…
Inverse magnetic catalysis and size-dependent effects on the chiral symmetry restoration
Luciano M. Abreu, Emerson B. S. Corrêa, Elenilson S. Nery
We investigate the combined finite-size and thermo-magnetic effects on the properties of the quark matter, in the context of the two-flavored Nambu--Jona-Lasinio model. In particul…
Unbinned multivariate observables for global SMEFT analyses from machine learning
Raquel Gomez Ambrosio, Jaco ter Hoeve, Maeve Madigan +2
Theoretical interpretations of particle physics data, such as the determination of the Wilson coefficients of the Standard Model Effective Field Theory (SMEFT), often involve the i…
High-precision muon decay predictions for ALP searches
P. Banerjee, A. M. Coutinho, T. Engel +3
We present an improved theoretical prediction of the positron energy spectrum for the polarised Michel decay . In addition to the full next-to-next-to-leadin…
Schwinger-Dyson truncations in the all-soft limit: a case study
A. C. Aguilar, M. N. Ferreira, B. M. Oliveira +1
We study a special Schwinger-Dyson equation in the context of a pure SU(3) Yang-Mills theory, formulated in the background field method. Specifically, we consider the corresponding…
Long-lived heavy neutral leptons with a displaced shower signature at CMS
Giovanna Cottin, Juan Carlos Helo, Martin Hirsch +3
We study the LHC discovery potential in the search for heavy neutral leptons (HNL) with a new signature: a displaced shower in the CMS muon detector, giving rise to a large cluster…
Electroweak Baryogenesis: The Scalar Singlet Strikes Back
E. Fernández-Martínez, J. López-Pavón, J. M. No +2
We perform a thorough scan of the parameter space of a general singlet scalar extension of the Standard Model to identify the regions which can lead to a strong first-order phase t…
Dark matter in the Scotogenic model with spontaneous lepton number violation
Valentina De Romeri, Jacopo Nava, Miguel Puerta +1
Scotogenic models constitute an appealing solution to the generation of neutrino masses and to the dark matter mystery. In this work we consider a version of the Scotogenic model t…
Charged pseudoscalar and vector meson masses under strong magnetic fields in an extended NJL model
J. P. Carlomagno, D. Gomez Dumm, M. F. Izzo Villafañe +2
The mass spectrum of and mesons in the presence of a static uniform magnetic field is studied within a two-flavor NJL-like model. We improve previous calculati…
Quantum jet clustering with LHC simulated data
Jorge J. Martínez de Lejarza, Leandro Cieri, Germán Rodrigo
We study the case where quantum computing could improve jet clustering by considering two new quantum algorithms that might speed up classical jet clustering algorithms. The first…
Evolution of charm-meson ratios in an expanding hadron gas
Eric Braaten, Roberto Bruschini, Li-Ping He +2
We study the time evolution of the numbers of charm mesons after the kinetic freeze-out of the hadron gas produced by a central heavy-ion collision. The react…
