Experiments and phenomenology of electric dipole moments Open
The Standard Model (SM) is the best description of fundamental particles and their interactions we have to date. From this theory, all phenomena in the macroscopic world (except for gravity) can be explained, and it has successfully predic…

The anomalous Lagrangian in ChPT at NNLO Open
The anomalous Lagrangian in mesonic Chiral Perturbation Theory, of odd intrinsic parity, is determined to next-to-next-to-leading order thereby completing the order $p^8$ Lagrangian. A schematic view of its construction with the MINIBAR pa…

The anomalous chiral Lagrangian at order p8 Open
A bstract We derive the order p 8 Lagrangian of odd intrinsic parity for mesonic chiral perturbation theory, and provide the resulting operator basis in the supplementary material. Neglecting the non-zero singlet trace, we find 999 operato…

CTD2022: One person's trash is another person's treasure: expanding physics reach with unused tracks Open
The physics reach of the LHCb detector can be extended by reconstructing particles with a long lifetime that decay downstream of the dipole magnet, using only hits in the furthest tracker from the interaction point. This allows for electro…

W-boson mass and electric dipole moments from colour-octet scalars Open
New coloured scalars in the Manohar-Wise model give sizeable contributions to the Electric Dipole Moment (EDM) of the neutron through one-loop and two-loop diagrams, computed in Reference [1]. Contributions from neutral scalars cancel out …

Improved experimental layout for dipole moment measurements at the LHC Open
The electric and magnetic dipole moment of charm and bottom baryons can be measured for the first time by using bent crystal technology at the LHC. The experimental method, proposed in recent years, suffers from limited statistics, which d…

Electric dipole moments from colour-octet scalars Open
We present the contributions to electric dipole moments (EDMs) induced by the Yukawa couplings of an additional electroweak doublet of colour-octet scalars. The full set of one-loop diagrams and the enhanced higher-order effects from Barr-…

Progress towards the first measurement of charm baryon dipole moments Open
Electromagnetic dipole moments of short-lived particles are sensitive to\nphysics within and beyond the Standard Model of particle physics but have not\nbeen accessible experimentally to date. To perform such measurements it has\nbeen prop…

Improved bounds on heavy quark electric dipole moments Open
New bounds on the electric dipole moment (EDM) of charm and bottom quarks are\nderived using the stringent limits on their chromo-EDMs. The new limits,\n$|d_c|<1.5\\times10^{-21}\\:e\\,\\text{cm}$ and $|d_b|< 1.2\\times\n10^{-20}\\:e\\,\\t…
