Combining experimental data from the LHC, low-energy precision observables, flavor measurements and astrophysical data, we analyze various incarnations of Supersymmetry (SUSY). This work is done within the MasterCode framework. We find that simple SUSY models are in agreement with all experimental data. We obtain predictions where the LHC has the best chances to find SUSY and where the direct...

Many supersymmetry models feature gauginos and also leptons with masses less than a few hundred GeV. These can give rise to direct pair production rates at the LHC that can be observed in the data sample recorded by the ATLAS detector. The talk presents results from searches for gaugino and slepton pair production in final states with leptons, and were performed with pp collisions at a...

.Despite the absence of experimental evidence, weak scale supersymmetry remains one of the best motivated and studied Standard Model extensions. This talk summarises recent ATLAS results on inclusive searches for supersymmetric squarks and gluinos, including third generation squarks produced in the decay of gluinos. The searches involve final states containing jets, missing transverse momentum...

The large set of proton-proton collision data recorded in 2016 at a centre-of-mass energy of 13 TeV is the basis for first results on electroweak production of supersymmetric particles in LHC Run 2. CMS results on the production of chargino / neutralino pairs are presented based on the analysis of final states with one or more leptons and interpreted under several assumptions for the decay...

We examine in detail the current LHC coverage of signatures arising from the R-Parity-violating Minimal Supersymmetric Standard Model. We take into account all experimental analyses for prompt signatures within this context, both explicit searches for RPV signals as well as other analyses containing applicable experimental signatures. These are contrasted with well-motivated phenomenological...

The almost pure Higgsino, however, is known to be a very challenging target at the LHC.
I will show that improvement of tracking technique of disappearing tracks can significantly increase the sensitivity for the Higgsino.
I will also discuss a future 33 TeV collider can probe the 1 TeV Higgsino, which is the most interesting... -

The status of most recent measurements of the Standard Model Higgs boson production and properties are presented in this talk. The studies are based on data recorded by the CMS experiment during the 2016 and include an overview of the results of bosonic and fermionic Higgs boson decays, with a focus on the Higgs boson produced in the association to top quark pair and production with single top quark.

We consider extended scalar sectors of the Standard Model as ultraviolet–complete motivations for studying the effective Higgs self–interaction operators of the Standard Model effective field theory. We investigate all motivated heavy scalar models which generate the dimension–6 effective operator, |H|^6, at tree level and proceed to identify the full set of tree–level dimension–six operators...

In this talk, we discuss a scenario to generate flavor violating $Z'$ interactions at one loop level, by introducing $U(1)_{\mu-\tau}$(-like) gauge symmetry, extra vectorlike quark doublets $Q'_a$ and singlet scalar $\chi$. Both $Q'_a$ and $\chi$ are charged under $U(1)_{\mu-\tau}$ and carry odd dark $Z_2$ parity. Assuming that $\chi$ is the dark matter (DM) of the universe and imposing...

I will propose new-type grand unified theories (GUTs) based on GUT gauge groups broken to their special subgroups as well as their regular subgroups. In the framework, to obtain the Standard Model (SM), 4D gauge anomaly cancellation restricts the minimal number of generations of the 4D SM Weyl fermions. In this talk, I will show that in an SU(16) GUT on 6D orbifold space whose GUT group is...

We revisit the non-thermal gravitino production at the (p)reheating stage after inflation. Particular attention is paid to large-field inflation models with a $\mathbb{Z}_2$ symmetry, for which the previous perturbative analysis is inapplicable; and inflation models with a stabilizer superfield, which have not been studied non-perturbatively. It is found that in single-superfield inflation...

The Two-Higgs-doublet model (2HDM) is one of the most studied extensions of the Standard Model. But just as the other popular "New Physics" models, it gets more and more constrained by recent experimental progress, especially by the LHC data. For all four 2HDM types with a softly broken Z2 symmetry, we present updated results of global analyses obtained with the open-source HEPfit code. We...

However, assuming that a type-II 2HDM arises as an effective theory at

completion, where the quartic couplings of the 2HDM potential are
related to the gauge couplings of the Standard Model (SM), the... -

The observation of a Higgs-like boson with a mass near 125 GeV/c2 at the Large Hadron Collider raises a critical question of whether the new particle is in fact the SM Higgs boson. Searches for non-SM Higgs boson production and its decay modes are therefore complementary. I will report the searches for extended Higgs sectors performed with the CMS detector. I will focus on Dark Susy and NMSSM...

We investigate the phenomenology of Composite 2-Higgs Doublet Models (C2HDMs) of various Yukawa types based on the global symmetry breaking SO(6)→SO(4)×SO(2). The kinetic part and the Yukawa Lagrangian are constructed in terms of the pseudo Nambu-Goldstone Boson (pNGB) matrix and a 6-plet of fermions under SO(6). The scalar potential is assumed to be the same as that of the Elementary 2-Higgs...

I will discuss the structure of the loop corrections in the case of the non-linear EW effective theory and compare it with the low-energy contributions from the exchange of heavy resonances. The convenience of using either the non-linear HEFT or the linear SMEFT will depend on the interplay of the scales that control these two types of contributions.

We revisit the decoupling effects associated with heavy particles in the renormalization group running of the vacuum energy in a mass-dependent renormalization scheme. We find the running of the vacuum energy stemming from the Higgs condensate in the entire energy range and show that it behaves as expected from the simple dimensional arguments meaning that it exhibits the quadratic sensitivity...
