DESCRIPTION:Speakers: Dr. SALDANA\, Ulises (MPI-K)\nWe will talk about a n
 ovel way to avoid FCNC's at tree level in any multi-scalar extension of th
 e Standard Model. This approach called Singular Alignment consists in taki
 ng all Yukawa matrices to be singularly aligned in flavor space. We mean b
 y this that the Yukawa matrices are given as linear combinations of the ra
 nk 1 matrices that appear in the singular value decomposition of the mass 
 matrix. We then discuss the application of this alignment to a 4-Higgs-dou
 blet model in which each Higgs doublet gives mass to one of the fermion se
 ts {𝑚𝑡}\, {𝑚𝑏\,𝑚𝜏\,𝑚𝑐}\, {𝑚𝜇\,𝑚𝑠}\, an
 d {𝑚𝑑\,𝑚𝑢\,𝑚𝑒}. The sets have the feature that within ea
 ch of them the masses are similar. Our model explains the mass hierarchies
  of the sets by hierarchies of the vacuum expectation values of the Higgs 
 doublets associated to them. All Yukawa couplings are therefore of order o
 ne. Neutrino masses could be generated by a type-I seesaw mechanism with P
 eV-scale singlet neutrinos. Finally\, we provide the smoking gun for testi
 ng the realization of this model in nature.\n\nhttp://indico.fuw.edu.pl/co

SUMMARY:b -> sl+l- Transitions in THDM with generic Yukawa couplings

DESCRIPTION:Speakers: Dr. WIEGAND\, Christoph (University of Bern)\nI will
  present our results on $b\\to s\\mu^+\\mu^-$ transitions and possible cor
 relations with the anomalous magnetic moment of the muon ($a_\\mu$) within
  Two-Higgs-Doublet models with generic Yukawa couplings\, including the po
 ssibility of right-handed neutrinos. We performed the matching on the rele
 vant effective Hamiltonian and calculated the leading one-loop effects for
  $b\\to s\\ell\\ell^{(\\prime)}$\, $b\\to s\\gamma$\, $\\Delta B=\\Delta S
 =2$\, $b\\to s\\nu\\bar\\nu$ and $\\ell\\to\\ell^\\prime\\gamma$ transitio
 ns in a general $R_\\xi$ gauge. Concerning the phenomenology\, we found th
 at an explanation of the hints for new physics in $b\\to s\\mu^+\\mu^-$ da
 ta is possible once right-handed neutrinos are included. If lepton flavour
  violating couplings are allowed\, one can account for the discrepancy in 
 $a_\\mu$ as well. However\, only a small portion of parameter space gives 
 a good fit to $b\\to s\\mu^+\\mu^-$ data and the current bound on $h\\to\\
 tau\\mu$ requires the mixing between the neutral Higgses to be very small 
 if one aims at an explanation of $a_\\mu$.\n\nhttp://indico.fuw.edu.pl/con
