Focus topics for the ECFA study on Higgs / Top / EW factories / de Blas, Jorge (Granada U.) ; Koppenburg, Patrick (Nikhef, Amsterdam) ; List, Jenny (DESY) ; Maltoni, Fabio (Louvain U.) ; Maestre, Juan Alcaraz (Madrid, CIEMAT) ; Alimena, Juliette (DESY) ; Alison, John (Carnegie Mellon U.) ; Azzi, Patrizia (INFN, Padua) ; Azzurri, Paolo (INFN, Pisa) ; Bagnaschi, Emanuele (CERN ; INFN, Italy) et al.
In order to stimulate new engagement and trigger some concrete studies in areas where further work would be beneficial towards fully understanding the physics potential of an $e^+e^-$ Higgs / Top / Electroweak factory, we propose to define a set of focus topics. [...]

Interpreting LHCb's $\Lambda_b\to \Lambda_c\tau\bar\nu$ measurement and puzzles in semileptonic $\Lambda_b$ decays / Bernlochner, Florian U. (Bonn U.) ; Ligeti, Zoltan (LBL, Berkeley ; UC, Berkeley) ; Papucci, Michele (Caltech) ; Robinson, Dean J. (LBL, Berkeley ; UC, Berkeley)
Normalizing the recent LHCb measurement of $\Lambda_b \to \Lambda_c \tau \bar\nu$ to the standard model (SM) prediction for the $\Lambda_b \to \Lambda_c \mu \bar\nu$ rate, instead of a LEP measurement, provides a more consistent comparison with the SM prediction for the lepton flavor universality ratio $R(\Lambda_c)$. This modestly increases $R(\Lambda_c)$ compared to the quoted LHCb result, such that it no longer hints at a suppression compared to the SM, which would be hard to accommodate in new physics scenarios that enhance $R(D^{(*)})$. [...]

Theoretical challenges for flavor physics / Grossman, Yuval (Cornell U., LEPP) ; Ligeti, Zoltan (LBL, Berkeley ; UC, Berkeley)
We discuss some highlights of the FCC-ee flavor physics program. It will help to explore various aspects of flavor physics: to test precision calculations, to probe nonperturbative QCD methods, and to increase the sensitivity to physics beyond the standard model. [...]

HAMMER: Reweighting tool for simulated data samples / Duell, Stephan (Bonn U.) ; Bernlochner, Florian (Bonn U.) ; Ligeti, Zoltan (LBL, Berkeley) ; Papucci, Michele (CERN ; LBL, Berkeley) ; Robinson, Dean (UC, Berkeley)
Modern flavour physics experiments, such as Belle II or LHCb, require large samples of generated Monte Carlo events. Monte Carlo events often are processed in a sophisticated chain that includes a simulation of the detector response. [...]

TASI Lectures on Flavor Physics / Ligeti, Zoltan (LBNL, Berkeley)
These notes overlap with lectures given at the TASI summer schools in 2014 and 2011, as well as at the European School of High Energy Physics in 2013. This is primarily an attempt at transcribing my hand-written notes, with emphasis on topics and ideas discussed in the lectures. [...]

On the Universality of CP Violation in Delta F = 1 Processes / Gedalia, Oram (Weizmann Inst.) ; Kamenik, Jernej F. (Stefan Inst., Ljubljana ; Ljubljana U.) ; Ligeti, Zoltan (LBL, Berkeley) ; Perez, Gilad (Weizmann Inst. ; CERN)
We show that new physics that breaks the left-handed SU(3)_Q quark flavor symmetry induces contributions to CP violation in Delta F = 1 processes which are approximately universal, in that they are not affected by flavor rotations between the up and the down mass bases. Therefore, such flavor violation cannot be aligned, and is constrained by the strongest bound from either the up or the down sectors. [...]

Implications of the LHCb Evidence for Charm CP Violation / Isidori, Gino (CERN ; Frascati) ; Kamenik, Jernej F. (Stefan Inst., Ljubljana ; Ljubljana U.) ; Ligeti, Zoltan (LBL, Berkeley) ; Perez, Gilad (CERN ; Weizmann Inst.)
The LHCb collaboration recently announced preliminary evidence for CP violation in D meson decays. We discuss this result in the context of the standard model (SM), as well as its extensions. [...]

Comment on measuring the t-tbar forward-backward asymmetry at ATLAS and CMS / Arguin, Jean-François ; Freytsis, Marat ; Ligeti, Zoltan
We suggest a new possibility for ATLAS and CMS to explore the t-tbar forward-backward asymmetry measured at the Tevatron, by attempting to reconstruct t-tbar events, with one of the tops decaying semileptonically in the central region (|\eta| < 2.5) and the other decaying hadronically in the forward region (|\eta| > 2.5).

Status of SIMBA / Bernlochner, Florian U. (Humboldt U., Berlin) ; Lacker, Heiko (Humboldt U., Berlin) ; Ligeti, Zoltan (LBL, Berkeley) ; Stewart, Iain W. (MIT, LNS) ; Tackmann, Frank J. (MIT) ; Tackmann, Kerstin (CERN)
The goal of the SIMBA collaboration is to provide a global fit to the available data in inclusive B -> X_s gamma and B -> X_u l nu decays. [...]
