A facility to Search for Hidden Particles at the CERN SPS: the SHiP physics case

S Alekhin, W Altmannshofer, T Asaka… - Reports on progress …, 2016 - iopscience.iop.org
This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP
(search for hidden particles) experiment is intended to hunt for new physics in the largely …

-violating baryon oscillations

D McKeen, AE Nelson - Physical Review D, 2016 - APS
We enumerate the conditions necessary for CP violation to be manifest in nn¯ oscillations
and build a simple model that can give rise to such effects. We discuss a possible …

Baryogenesis from oscillations of charmed or beautiful baryons

K Aitken, D McKeen, T Neder, AE Nelson - Physical Review D, 2017 - APS
We propose a model for CP-violating oscillations of neutral, heavy-flavor baryons into
antibaryons at rates which are within a few orders of magnitude of their lifetimes. The flavor …

New ideas in baryogenesis: a snowmass white paper

G Elor, J Harz, S Ipek, B Shakya, N Blinov… - arXiv preprint arXiv …, 2022 - arxiv.org
The Standard Model of Particle Physics cannot explain the observed baryon asymmetry of
the Universe. This observation is a clear sign of new physics beyond the Standard Model …

Baryogenesis via particle-antiparticle oscillations

S Ipek, J March-Russell - Physical Review D, 2016 - APS
CP violation, which is crucial for producing the baryon asymmetry of the Universe, is
enhanced in particle-antiparticle oscillations. We study particle-antiparticle oscillations [of a …

Baryogenesis via mesino oscillations

A Ghalsasi, D McKeen, AE Nelson - Physical Review D, 2015 - APS
We propose a new mechanism for baryogenesis at the 1–200 MeV scale. Enhancement of
charge parity (CP) violation takes place via interference between oscillations and decays of …

h→ γγ in U (1) R-lepton number model with a right-handed neutrino

S Chakraborty, AK Datta, S Roy - Journal of High Energy Physics, 2015 - Springer
A bstract We perform a detailed study of the signal rate of the lightest Higgs boson in the
diphoton channel (μ γγ), recently analyzed by both the ATLAS and CMS collaborations at …

Charting generalized supersoft supersymmetry

S Chakraborty, A Martin, TS Roy - Journal of High Energy Physics, 2018 - Springer
A bstract Without any shred of evidence for new physics from LHC, the last hiding spots of
natural electroweak supersymmetry seem to lie either in compressed spectra or in spectra …

Constrained Dirac gluino mediation

D Busbridge - arXiv preprint arXiv:1408.4605, 2014 - arxiv.org
We perform a comparison study of the Constrained Minimal Supersymmetric Standard
Model and Constrained General Gauge Mediation with and without a heavy Dirac gluino …

Light top squarks in a lepton number model with a right handed neutrino and the LHC

S Chakraborty, AK Datta, K Huitu, S Roy, H Waltari - Physical Review D, 2016 - APS
We investigate the phenomenology of top squarks at the Large Hadron Collider (LHC) in a
supersymmetric model where lepton number is identified with an approximate U (1) R …
