Gamma Factory -- a tool-driven revolution?
In this talk, I shall present the Gamma Factory project, being developed at CERN over the last 7 years. Its goal is to broaden significantly the present CERN research programme by including a new component which can be open by the novel-type light source. The proposed, partially-stripped-ion-beam-driven light source is the backbone of the Gamma Factory project. It could be realized at CERN by re-using the infrastructure of the already existing accelerators and by profiting from the recent progress in the laser technology. It could extend the scientific life of the LHC storage rings beyond its HL-LHC phase. Gamma Factory could push the intensity limits of the presently operating light-sources by at least 7 orders of magnitude, reaching the flux of up to 10^18 photons/s, in the particularly interesting gamma-ray energy domain of 0.1 — 400 MeV, which is presently nor accessible to the FEL photon sources. The partially stripped ion beams, the unprecedented-intensity energy-tuned gamma beams, together with the gamma-beam-driven secondary beams of polarized positrons, polarized muons, neutrinos, neutrons, and radioactive ions constitute the basic research tools of the Gamma Factory. A broad spectrum of new research opportunities, in a vast domain of uncharted fundamental and applied physics territories, could be opened by the Gamma Factory. Examples of new research opportunities and the status of the project development will be presented in this talk.
The High Energy Physics group at UCL invites applications for a
Postdoctoral Research Fellow position in Proton Beam Therapy (PBT) diagnostics development.
A new, ultraprecise measurement of the subatomic muon particle’s anomalous magnetic moment, conducted at US-based Fermilab and involving researchers from UCL, reinforces a discrepancy between theory and experiment that physicists can’t explain, potentially hinting at new physics.
We are keen to support a limited number of strong candidates in applying for Research Fellowships.
If your profile and interests match our activities, we would be very interested to hear from you.

Constraining the SMEFT with Right-Handed Neutrinos at FCC-ee
The existence of right-handed neutrinos (RHNs), or heavy neutral leptons (HNLs), is strongly motivated by the observation of small but finite neutrino masses and mixings. In this work, we have extended the Standard Model (SM) particle content with a pair of gauge-singlet fermions, which can be Dirac or Majorana in nature. Adopting a model-independent effective field theory (EFT) framework, more specifically NRSMEFT, we consider all possible operators of different Lorentz structures i.e., scalar-pseudoscalar (SP), vector-axial vector (VA), and tensor-axial tensor (TAT) types upto mass dimension 6. With these operators, we analyze the future electron positron circular collider (FCC-ee) prospects and constrain the corresponding new physics (NP) cut-off scale ΛNP in the monophoton channel with √s = 91.2 GeV at 100 ab−1 as well as √s = 240 GeV at 5 ab−1 integrated luminosities.

The latest result in the search for Higgs pair production in ATLAS at the LHC, in the 4b final state, is now out:
with big contributions from the UCL ATLAS team, including the co-editor of the journal publication.
Higgs pair production (the production of two Higgs bosons in a single proton-proton collision at the LHC)
is a rare process that can shed light on the properties of the Higgs boson and particularly the Higgs field
potential (the famous "Mexican hat"). The Electroweak Phase Transition, one of the most dramatic and
defining moments in the evolution of our Universe, happened around 1 picosecond (one billionth of a
millisecond!) after the Big Bang. The shape of the Higgs field potential is intricately linked to that moment.
