Minimal cascade decay of the top quark through a new scalar
Bogdan A. Dobrescu, Max H. Fieg, Alessandro Russo
We explore a possible decay of the top quark into a new scalar plus a charm quark. The decay is mediated by a dimension-5 operator that may be generated by the exchange of a…
Cornering MeV-GeV Axions and Dark Photons with LDMX
Sarah Gaiser, Alessandro Russo, Philip Schuster
Axion-like particles (ALPs), the QCD axion, and dark photons in the MeV-GeV mass range are motivated by various dark matter models and the strong CP problem, and are ubiquitous in…
Hydrogen 21 cm Constraints on the Photon's Spin Scale
Aidan Reilly, Alessandro Russo, Philip Schuster +1
We explore the fundamental but untested possibility that the photon is a continuous spin particle (CSP) with a small but non-zero spin Casimir . When , the familiar pol…
Phenomenology of photons-enriched semi-visible jets
Cesare Cazzaniga, Alessandro Russo, Emre Sitti +1
This Letter proposes a new signature for confining dark sectors at the LHC. Under the assumption of a QCD-like hidden sector, hadronic jets containing stable dark bound states orig…
Mutually elusive: vectorlike antileptons and leptoquarks
Innes Bigaran, Bogdan A. Dobrescu, Alessandro Russo
We study the properties of vectorlike fermions that have the same gauge charges as the Standard Model lepton doublets, but opposite lepton number. These antileptons undergo decays…
