1. New axion searches at flavor factories / Vidal, Xabier ; Mariotti, Alberto ; Redigolo, Diego ; Sala, Filippo ; et al
We assess the impact of searches at flavor factories for new neutral resonances that couple to both photons and gluons. [...]

2. Learning to pinpoint effective operators at the LHC: a study of the t t ¯ b b ¯ $$ \mathrm{t}\overline{\mathrm{t}}\mathrm{b}\overline{\mathrm{b}} $$ signature / D’Hondt, Jorgen ; Mariotti, Alberto ; Mimasu, Ken ; Moortgat, Seth ; et al
In the context of the Standard Model effective field theory (SMEFT), we study the LHC sensitivity to four fermion operators involving heavy quarks by employing cross section measurements in the t t ¯ b b ¯ $$ t\overline{t}b\overline{b} $$ final state. [...]

3. Singlet-Doublet dark matter freeze-in: LHC displaced signatures versus cosmology / Calibbi, Lorenzo ; Lopez-Honorez, Laura ; Lowette, Steven ; Mariotti, Alberto
We study the Singlet-Doublet dark matter model in the regime of feeble couplings, where the dark matter abundance is obtained via the freeze-in mechanism. [...]

4. New LHC bound on low-mass diphoton resonances / Mariotti, Alberto ; Redigolo, Diego ; Sala, Filippo ; Tobioka, Kohsaku
We derive a new bound on diphoton resonances using inclusive diphoton cross section measurements at the LHC, in the so-far poorly constrained mass range between the ϒ and the SM Higgs. [...]

5. SUSY meets her twin / Katz, Andrey ; Mariotti, Alberto ; Pokorski, Stefan ; Redigolo, Diego ; et al
We investigate the general structure of mirror symmetry breaking in the Twin Higgs scenario. [...]

6. Cornering diphoton resonance models at the LHC / Backović, Mihailo ; Kulkarni, Suchita ; Mariotti, Alberto ; Sessolo, Enrico ; et al
We explore the ability of the high luminosity LHC to test models which can explain the 750 GeV diphoton excess. [...]

7. Di-photon excess illuminates dark matter / Backović, Mihailo ; Mariotti, Alberto ; Redigolo, Diego
We propose a simplified model of dark matter with a scalar mediator to accommodate the di-photon excess recently observed by the ATLAS and CMS collaborations. [...]

8. Signatures of top flavour-changing dark matter / D’Hondt, Jorgen ; Mariotti, Alberto ; Mawatari, Kentarou ; Moortgat, Seth ; et al
We develop the phenomenology of scenarios in which a dark matter candidate interacts with a top quark through flavour-changing couplings, employing a simplified dark matter model with an s -channel vector-like mediator. [...]

9. Singlet-Doublet model: dark matter searches and LHC constraints / Calibbi, Lorenzo ; Mariotti, Alberto ; Tziveloglou, Pantelis
The Singlet-Doublet model of dark matter is a minimal extension of the Standard Model with dark matter that is a mixture of a singlet and a non-chiral pair of electroweak doublet fermions. [...]

10. Z -peaked excess in goldstini scenarios / Liew, Seng Pei ; Mariotti, Alberto ; Mawatari, Kentarou ; Sakurai, Kazuki ; et al
We study a possible explanation of a 3.0 σ excess recently reported by the ATLAS Collaboration in events with Z -peaked same-flavour opposite-sign lepton pair, jets and large missing transverse momentum in the context of gauge-mediated SUSY breaking with more than one hidden sector, the so-called goldstini scenario.
