Electroweak and Single Top-Quark Conspiracy in Current LHC Data
Christoph Englert, Roman Kogler, Michael Spannowsky
Recent LHC measurements of electroweak single top-quark and top-quark associated Higgs boson production show a number of rate shifts, while related multiboson channels remain close…
Looking inside jets: an introduction to jet substructure and boosted-object phenomenology
Simone Marzani, Gregory Soyez, Michael Spannowsky
The study of the internal structure of hadronic jets has become in recent years a very active area of research in particle physics. Jet substructure techniques are increasingly use…
Potential Blind Directions at TeraZ
Mikael Chala, Juan Carlos Criado, Michael Spannowsky
The next generation of high-luminosity electron-positron colliders, such as FCC-ee and CEPC operating at the pole (TeraZ), is expected to deliver unprecedented precision in ele…
Differentiating Dimension-6 and Dimension-8 Effects in SMEFT at the HL-LHC
Manimala Mitra, Shakeel Ur Rahaman, Subham Saha +1
We study dimension-eight effects in the Standard Model Effective Field Theory extended by right-handed neutrinos (SMEFT). Using the Hilbert series formalism, we derive the comp…
Weak boson probes of Higgs unitarity restoration at 10 TeV parton colliders
Christoph Englert, Wrishik Naskar, Andrew D. Pilkington +1
Higgs coupling deviations, at levels accessible to the high-luminosity LHC, can imply a phenomenological no-lose theorem for the next generation of collider facilities. Correlating…
Sensitivity of -boson measurements to low-mass right-handed neutrinos
Rodrigo Alonso, Sam Bates, Chris Hays +2
A low-mass right-handed neutrino could interact with electroweak bosons via mixing, a mediator particle, or loop corrections. Using an effective field theory, we determine constrai…
