Journal Article

We perform a likelihood analysis of the minimal anomaly-mediated supersymmetry-breaking (mAMSB) model using constraints from cosmology and accelerator experiments. We find that either a wino-like or a Higgsino-like neutralino LSP, χ~01χ~10 , may prov... Read More about Likelihood analysis of the minimal AMSB model.

Likelihood analysis of supersymmetric SU(5) GUTs (2017)
Journal Article
Bagnaschi, E., Costa, J., Sakurai, K., Borsato, M., Buchmueller, O., Cavanaugh, R., …Weiglein, G. (2017). Likelihood analysis of supersymmetric SU(5) GUTs. The European Physical Journal C, 77(2), Article 104. https://doi.org/10.1140/epjc/s10052-017-4639-6

We perform a likelihood analysis of the constraints from accelerator experiments and astrophysical observations on supersymmetric (SUSY) models with SU(5) boundary conditions on soft SUSY-breaking parameters at the GUT scale. The parameter space of t... Read More about Likelihood analysis of supersymmetric SU(5) GUTs.

Tagging a monotop signature in natural SUSY (2017)
Journal Article
Gonçalves, D., Sakurai, K., & Takeuchi, M. (2017). Tagging a monotop signature in natural SUSY. Physical Review D, 95(1), Article 015030. https://doi.org/10.1103/physrevd.95.015030

We study the feasibility of probing a region of natural supersymmetry where the stop and Higgsino masses are compressed. Although this region is most effectively searched for in the monojet channel, this signature is present in many other nonsupersym... Read More about Tagging a monotop signature in natural SUSY.

Interpreting 750 GeV diphoton excess in plain NMSSM (2016)
Journal Article
Badziak, M., Olechowski, M., Pokorski, S., & Sakurai, K. (2016). Interpreting 750 GeV diphoton excess in plain NMSSM. Physics Letters B, 760, 228-235. https://doi.org/10.1016/j.physletb.2016.06.057

NMSSM has enough ingredients to explain the diphoton excess at 750 GeV: singlet-like (pseudo) scalar (a) s and higgsinos as heavy vector-like fermions. We consider the production of the 750 GeV singlet-like pseudo scalar a from a decay of the doublet... Read More about Interpreting 750 GeV diphoton excess in plain NMSSM.

Search for sphalerons in proton-proton collisions (2016)
Journal Article
Ellis, J., & Sakurai, K. (2016). Search for sphalerons in proton-proton collisions. Journal of High Energy Physics, 2016(4), Article 86. https://doi.org/10.1007/jhep04%282016%29086

In a recent paper, Tye and Wong (TW) have argued that sphaleron-induced transitions in high-energy proton-proton collisions should be enhanced compared to previous calculations, based on a construction of a Bloch wave function in the periodic sphaler...
