594. Searches for electroweak production of supersymmetric gauginos and sleptons with the ATLAS detector

Supersymmetry is one of the most motivated Standard Model extensions. Despite the meticulous search during the LHC Run I, there is no evidence supporting this theory. Starting from 2015, LHC is performing a second data taking run with a higher center of mass energy (13 TeV), providing a great occasion for the search of beyond the Standard Model physics.
An important sector is the direct...

506. Charged Higgs bosons in supersymmetric extended Higgs sectors at the LHC

Dr Priyotosh Bandyopadhyay (Indian Institute of Technology Hyderabad)

parallel talk

We focus on the triplet and singlet extensions of minimal supersymmetric scenario, where we can see that the electro-weak contributions coming from the additional triplet and singlet are also important and comparable to the strong contributions. In the context of the observed Higgs like particle around 125 GeV, we look into the status of other Higgs bosons in the model. The possibility of...

606. Searches for supersymmetry in R-parity violating and long-lived signatures with the ATLAS detector

parallel talk

R-parity violation introduces many viable signatures to the search for supersymmetry at the LHC. The decay of supersymmetric particles can produce leptons or jets, while removing the missing transverse momentum signal common to traditional supersymmetry searches. Several supersymmetric models also predict massive long-lived supersymmetric particles. Such particles may be detected through...

499. Timing the pulses of BSM signals

In this work, we propose to use the timing information (new pico-second timing resolution with detector upgrades) to search for a broad class of BSM signals, such as Higgs decays to glueballs or SUSY long-lived particles.

623. Probing baryogenesis with displaced vertices at the LHC

parallel talk

In a large class of baryogenesis models, where the baryon asymmetry results from the out of equilibrium decay of new weak scale massive meta-stable particle. This is correlated to the proper decay length of the meta-stable particle being larger than 1 mm. We discuss the new search strategies for probing these long lived particles at the LHC with displaced vertices and MET mainly focusing on...

524. Searches for supersymmetry in final states with photons in CMS

Marius Teroerde (Rheinisch Westfaelische Tech. Hoch. (DE))

Results of searches for supersymmetry in events with one or more isolated photons are reported, based on a data set of pp collisions at sqrt(s)=13TeV, recorded by the CMS experiment. Specific searches target events that also feature large missing transverse energy, large hadronic activity and/or isolated leptons. These searches are particularly relevant in the context of gauge-mediated SUSY...

452. Supergravity Models with heavy scalars, SUSY Discovery at the LHC and HE-LHC and Gravitino Decay Constraints

Mr Amin Aboubrahim (Northeastern University)

07/05/2018, 18:00

parallel talk

We investigate the possibility of testing supergravity unified models with heavy scalar masses at the Large Hadron Collider. The analysis is carried out under the constraints that models produce the Higgs boson mass consistent with experiment and also produce dark matter consistent with WMAP and PLANCK experiments. A set of benchmarks in the supergravity parameter space are investigated using...

576. Bayesian analysis and naturalness of (Next-to-)Minimal Supersymmetric Models

Dr Dylan Harries (Charles University Prague)

parallel talk

In non-minimal supersymmetric (SUSY) models, additional tree-level
contributions to the Higgs mass provide a possible solution to the little
hierarchy problem of the minimal supersymmetric standard model (MSSM). This
has generated increased interest in models such as the next-to-MSSM (NMSSM),
on the grounds that they may be more natural than the MSSM. However,
traditional measures of...
