Axion-Photon Interaction from Nonminimal Dimension-5 Lorentz-Violating Operators
A. J. G. Carvalho, A. G. Dias, A. F. Ferrari +3
In this paper, we discuss various possible schemes for the perturbative generation of the axion-photon interaction term in different Lorentz-breaking extensions of QED, involving o…
Next-to-leading-order predictions for single vector-like quark production at the LHC
Giacomo Cacciapaglia, Alexandra Carvalho, Aldo Deandrea +5
We propose simulation strategies for single production of third generation vector-like quarks at the LHC, implementing next-to-leading-order corrections in QCD and studying in deta…
Single production of vector-like quarks with large width at the Large Hadron Collider
Alexandra Carvalho, Stefano Moretti, Dermot O'Brien +2
Vector-Like Quarks (VLQs) are predicted by several theoretical scenarios of new physics and, having colour quantum numbers, can copiously be produced at the Large Hadron Collider (…
On the reinterpretation of non-resonant searches for Higgs boson pairs
Alexandra Carvalho, Florian Goertz, Ken Mimasu +2
The detection of production of a pair of Higgs bosons before the end of LHC operation would be clear evidence of New Physics (NP). As searches for non-resonant production of Higgs…
Probing vector-like quark models with Higgs-boson pair production
Giacomo Cacciapaglia, Haiying Cai, Alexandra Carvalho +5
We investigate Higgs-boson pair production at the LHC when the final state system arises from decays of vector-like quarks coupling to the Higgs boson and the Standard Model quarks…
Analytical parametrization and shape classification of anomalous HH production in the EFT approach
Alexandra Carvalho, Martino Dall'Osso, Pablo de Castro Manzano +4
In this document we study the effect of anomalous Higgs boson couplings on non-resonant pair production of Higgs bosons () at the LHC. We explore the space of the five paramete…
Higgs Pair Production: Choosing Benchmarks With Cluster Analysis
Alexandra Carvalho, Martino Dall'Osso, Tommaso Dorigo +3
New physics theories often depend on a large number of free parameters. The precise values of those parameters in some cases drastically affect the resulting phenomenology of funda…
Gravity particles from Warped Extra Dimensions, predictions for LHC
Alexandra Carvalho
Warped Extra Dimension scenarios are a rich playground for phenomenology of heavy resonances at LHC. The Radion and the KK-graviton are inevitable signatures of this class of model…
