Interpreting the High-Recoil LUX-ZEPLIN Event with Bino-/Singlino-like and Higgsino Dark Matter
Subhojit Roy, Pedro Schwaller, Carlos E. M. Wagner
The LUX-ZEPLIN (LZ) experiment has recently reported a nuclear-recoil candidate at keV. We study two supersymmetric interpretations based on distinct neutralino coup…
Dark Energy and Neutrino Flavor from the Weak Axion
Pedro Bittar, Carlos E. M. Wagner
Dynamical dark energy offers an alternative to a cosmological constant with distinct observational signatures. However, the small energy density scale, Hubble-sized mass, and Planc…
Alignment and Enhanced Multi-Higgs Production
Subhojit Roy, Carlos E. M. Wagner
Contrary to conventional expectations, we identify a class of extended scalar-sector scenarios in which final states with two, three, or four Higgs bosons constitute the leading di…
Shedding Light on Dark Matter at the LHC with Machine Learning
Ernesto Arganda, Martín de los Rios, Andres D. Perez +3
We investigate a WIMP dark matter (DM) candidate in the form of a singlino-dominated lightest supersymmetric particle (LSP) within the -symmetric Next-to-Minimal Supersymmetri…
R-parity violation and 8 TeV four-jet events at the LHC
Pedro Bittar, Subhojit Roy, Carlos E. M. Wagner
The CMS Collaboration at the Large Hadron Collider (LHC) has observed two four-jet events with a total invariant mass of about 8 TeV; within each event, the jets can be paired into…
Self Consistent Thermal Resummation: A Case Study of the Phase Transition in 2HDM
Pedro Bittar, Subhojit Roy, Carlos E. M. Wagner
An accurate description of the scalar potential at finite temperature is crucial for studying cosmological first-order phase transitions (FOPT) in the early Universe. At finite tem…
Machine-Learning Analysis of Radiative Decays to Dark Matter at the LHC
Ernesto Arganda, Marcela Carena, Martín de los Rios +4
The search for weakly interacting matter particles (WIMPs) is one of the main objectives of the High Luminosity Large Hadron Collider (HL-LHC). In this work we use Machine-Learning…
Testing the lepton content of the proton at HERA and EIC
Leandro Da Rold, Anibal D. Medina, Subhojit Roy +1
Although protons are baryons with an overall vanishing lepton number, they possess a non-trivial leptonic content arising from quantum fluctuations which can be described by lepton…
Dark Matter searches with photons at the LHC
Subhojit Roy, Carlos E. M. Wagner
We unveil blind spot regions in dark matter (DM) direct detection (DMDD), for weakly interacting massive particles with a mass around a few hundred~GeV that may reveal interesting…
Model-independent searches for new physics in multi-body invariant masses
S. V. Chekanov, S. Darmora, W. Islam +2
Model-independent searches for physics beyond the Standard Model typically focus on invariant masses of two objects (jets, leptons or photons). In this study we explore opportuniti…
