A search for the resonant production of a heavy scalar X decaying into a Higgs boson and

a new lighter scalar S, through the process X$\rightarrow$ S ($b\bar{b}$) H($\gamma \gamma$), where the two photons are consistent with the Higgs boson decay, is performed. The search is conducted using 140 fb$^{-1}$ of LHC Run 2 data recorded by ATLAS. The mass space investigated in the analysis is 170... -

Deviations from the Standard Model have long been observed in semileptonic B-meson decays, notably b→ sll transitions, triggering speculations on potential New Physics effects in this sector. After the recent update of RK(*) and BR(B(s) → μμ) by the LHCb collaboration, the remaining significant deviations from the SM in FCNC B decays are found in the branching ratios of mesonic decays...

The pursuit of deviations from the Standard Model (SM) is prompted by the recognition of the model's known limitations. Some findings suggest possible violations of lepton universality. The identification of such deviations could potentially lead to a SM extension, adding Z' boson that interacts with leptons in a different manner.
The SM is also firmly grounded by the principle of Lorentz...

Since the existence of the Higgs boson has been experimentally confirmed by the ATLAS and CMS Collaborations, many of its properties have been measured with high precision. However, one of its main property, the shape of the Higgs potential, remains unknown. The Higgs pair production represents the most direct way of measuring this potential, and any excess observed could be a sign of new...

Une recherche de particules de matière noire produites en association avec un nouveau boson vecteur neutre est effectuée en utilisant des collisions de protons-protons à √s=13 TeV, correspondant à une luminosité intégrée de 140 fb−1 enregistrée par le détecteur ATLAS au Grand Collisionneur de Hadrons. Les désintégrations du boson Z′ en leptons légers de même saveur (e+e−/μ+μ−) sont étudiées...

of new massive particles in the Compact Muon Solenoid
(CMS) experiment at the Large Hadron Collider (LHC).
CMS is one of the four main experiments at the LHC,
where high energy proton-proton collisions are pro-
duced. New long-lived particles are predicted in several
extensions of the Standard Model (SM). In the model
considered,... -

The Standard Model (SM) cannot explain the composition of Dark Matter in the Universe. Some Beyond Standard Model theories predict the existence of a dark hidden sector which contain new hypothetical particles : stable particles in this sector are Dark Matter candidates. The new particles could weakly interact with Standard Model ones through a new interaction, and thus can be produced in...
