Aspects of CP violation in the H ZZ coupling at the LHC / Godbole, Rohini M (Centre for High Energy Physics, Indian Institute of Science, Bangalore, India) ; Miller, David J (Dept. of Physics and Astronomy, University of Glasgow, Glasgow, U.K.) ; Muehlleitner, M Margarete (CERN ; Laboratoire d’Annecy-Le-Vieux de Physique Theorique, LAPTH, France)
We examine the CP-conserving (CPC) and CP-violating (CPV) effects of a general $H ZZ$ coupling through a study of the process $H \ra Z Z^{(*)} \ra \ell^+ \ell^- \ell^{'+} \ell^{'-}$ at the LHC. We construct asymmetries that directly probe these couplings [...]

Measurement of the longitudinal polarization of the top quark in top-antitop events with the ATLAS experiment. / Hamilton, S (Tufts University)
Abstract: "We perform two measurements of the product of the top quark polarization and the leptonic spin analyzing power ("alpha_l * P) assuming that the polarization is introduced by either a CP conserving (CPC) or CP violating (CPV) production process. We perform this analysis by analyzing top-antitop events collected in 4.7 fb^-1 of proton-proton collision data at 7 TeV center of mass energy, recorded with the ATLAS detector at the Large Hadron Collider [...]

London ; CERN ; Shanghai Jiao Tong U.) ; He, Hong-Jian (Shanghai Jiaotong U. ; Tsinghua U., Beijing ; Peking U.) ; Xiao, Rui-Qing (King's Coll. London ; Shanghai Jiao Tong U.)
We study probes of neutral triple gauge couplings (nTGCs) via $Z^*\gamma$ production followed by off-shell decays $Z^*\to\nu\bar{\nu}$ at the LHC and future $pp$ colliders, including both CP-conserving (CPC) and CP-violating (CPV) couplings. We present the dimension-8 SMEFT operators contributing to nTGCs and derive the correct form factor formulation for the off-shell vertices $Z^*\gamma V^*$ ($V=Z,\gamma$) by matching them with the dimension-8 SMEFT operators.

Model-independent analysis of Higgs spin and CP properties in the process $e^+ e^- \to t \bar t \Phi$ / Godbole, R.M. (CERN ; Utrecht U.) ; Hangst, C. (KIT, Karlsruhe) ; Muhlleitner, M. (KIT, Karlsruhe) ; Rindani, S.D. (Ahmedabad, Phys. Res. Lab) ; Sharma, P. (Ahmedabad, Phys. Res. Lab)
In this paper we investigate methods to study the $t\bar{t}$ Higgs coupling. The spin and CP properties of a Higgs boson are analysed in a model-independent way in its associated production with a $t\bar{t}$ pair in high-energy $e^+e^-$ collisions. [...]

General Minimal Flavor Violation / Kagan, Alexander L (Cincinnati U.) ; Perez, Gilad (Weizmann Inst. ; YITP, Stony Brook) ; Volansky, Tomer (Princeton, Inst. Advanced Study) ; Zupan, Jure (CERN)
A model independent study of the minimal flavor violation (MFV) framework is presented, where the only sources of flavor breaking at low energy are the up and down Yukawa matrices. Two limits are identified for the Yukawa coupling expansion: linear MFV, where it is truncated at the leading terms, and nonlinear MFV, where such a truncation is not possible due to large third generation Yukawa couplings. [...]
