Chiral electroweak anomalies predict baryon (B) and lepton (L) violating fermion interactions, which can be dressed with large numbers of Higgs and gauge bosons. The estimation of the total B + L-violating rate from an initial two-particle state — potentially observable at colliders — has been the subject of an intense discussion, mainly centered on the resummation of boson emission, which is...
The recent years have shown an exciting development in the scientific commmunity due to the interplay between new methods from data science and artificial intelligence, increasing computational resources and physics. The fundamental object of our theories of nature is the Lagrangian whose form is determined by the symmetries found already. A famous and well-motivated extension of the SM...
We present a study of searching for massive long-lived particles at the MoEDAL detector. MoEDAL is sensitive to highly ionising objects such as magnetic monopoles or massive (meta-)stable charged particles and we focus on the latter in this talk. Requirements on triggering or reducing the cosmic-ray and cavern background, applied in the ATLAS and CMS analyses for long-lived particles, are not...
The assumption of a supersymmetry between bosons and fermions has been found capable of addressing many key issues in particle physics and gravity such as the cancellation of ultraviolet divergences in particle and gravitational scattering amplitudes as well as in the vacuum energy density, providing a solution to the hierarchy problem, evasion of the Coleman-Mandula theorem, construction of a...
A search for pair production of supersymmetric particles in events with two oppositely charged leptons and missing transverse momentum is reported. The data sample corresponds to an integrated luminosity of 35.9/fb of proton-proton collisions at 13 TeV collected with the CMS detector during the 2016 data taking period at the LHC. No significant deviation is observed from the predicted standard...
Phenomenological studies of SUSY models typically imply the sampling of multidimensional parameter spaces. Each parameter point needs to be checked against the available theoretical and experimental limits from indirect and direct SUSY searches. The constraints from direct electroweakino searches are particularly challenging due to the computational resources needed to calculate their...
Since constraints from LHC SUSY searches and direct detection experiments of dark matter become increasingly stringent, it becomes non-trivial task to find a SUSY model which can explain the muon g-2 anomaly and the nature of dark matter, simultaneously. In this talk, I will present a relatively simple SUSY model solving these two important issues, satisfying the LHC and other constraints. It...
We derive a useful formula for general SUSY and GUT mass spectra to satisfy the gauge coupling unification. This formula enables us to study concrete GUT models from the point of view of low energy SUSY spectrum, i.e. SUSY breaking scenarios. We apply our machinery to Minimal SU(5) and Orbifold SU(5) models and study the impact of low energy SUSY spectrum and SUSY breaking scenarios on the...
We present the current perspectives for SUSY at the LHC Run-II and at future colliders, as well as the current perspectives for SUSY Dark Matter in light of current and future direct detection experiments,in a phenomenological, Minimal Supersymmetric Standard Model with eleven parameters (pMSSM11) and in the subGUT-CMSSM.
The subGUT-CMSSM is a CMSSM-like scenario where the input scale, M_{in},...
We present a specific flavor symmetry structure in the MSSM in the trilinear soft terms at a SUSY breaking scale, exploring the consequences of it in flavor violation processes for the charged leptonic sector. Specifically we calculate at 1-loop level $BR(\tau \to \mu \gamma)$ and $BR(h^0\to \tau \mu)$ in connection with possible solutions of anomalous magnetic moment of the muon problem....
Vectorlike fermions are widely considered as an extension of the Standard Model (SM). They are approximately protected by a $Z_2$ symmetry and decay to an SM boson and a quark/lepton. Vectorlike quarks have been searched for at the LHC, while vectorlike lepton searches suffer from smaller production cross section.
I will talk about "MSSM4G scenario," which is an extension of MSSM by...
