Parrying Parity

Abstract

One Berkeleyan case for idealism, recently developed by Robert M. Adams, relies on a seeming disparity between our concepts of matter and mind. Thomas Reid’s critique of idealism directly challenges the alleged disparity. After highlighting the role of the disparity thesis in Adams’s updated Berkeleyan argument for idealism, this chapter offers an updated version of Reid’s challenge, and assesses its strength. What emerges from this historico-philosophical investigation is that a contemporary Reidian has much work to do to transpose her objections to Berkeley into good objections to Adams’s argument.

Generic loop effects of new scalars and fermions in b → sℓ+ℓ− and a vector-like 4th generation

“…In fact, it leads to correlated effects in Kaon physics [178] if one aims at explaining the slight tensions in B → πµ + µ − [179] simultaneously with the ones in b → s + − data. Furthermore, our setup and results can also be used for addressing the tension between theory and experiment in / [180,181] 12 . Here, as a special case of our generic approach, the MSSM has already been studied with the conclusion that it can provide a valid explanation of the anomaly [184][185][186].…”

On the importance of NNLO QCD and isospin-breaking corrections in $$\varepsilon '/\varepsilon $$

“…Our analysis and in particular the comparison of the results in (14) and (15) as well as the Table 2 demonstrates the importance of NNLO QCD corrections and of isospin-breaking effects. Anticipating that the new RBC-UKQCD analysis will find B (1/2) 6 (m c ) < 1.0 as hinted by DQCD, the values of ε /ε in the SM will be significantly below the data.…”

“…In Table 2 below, we have set Im λ t = 1.4 × 10 −4 . For the result in (14) and (15) we have used Im λ t = (1.43 ± 0.04) × 10 −4 , based on recent analyses of the unitarity triangle by the bayesians ("UTfitter") and frequentists ("CKMfitter") that can be found in [41] and [42], respectively. The error budget, discussed in Appendix B and summarized in Table 6, would imply the parametric theoretical error of 2.3 × 10 −4 .…”

“…In contrast to the expected RBC-UKQCD result, the ChPT analysis includes isospinbreaking and QED corrections but the known difficulties in matching long-distance and short-distance contributions in this approach imply a large uncertainty. In particular, the absence of the so-called meson evolution in ChPT that suppresses ε /ε within the DQCD approach [12,14] is responsible for the poor matching and the large value of ε /ε in (2). The DQCD analysis in [21] demonstrates on the example of BSM matrix elements in K 0 − K 0 mixing that the effects of meson evolution are included in the present LQCD calculations.…”

“…Now all the 2015 analyses of ε /ε and the one in [18] used the known Wilson coefficients at the NLO level [27][28][29][30][31][32] in the naive dimensional regularization (NDR) scheme [33]. But already in [34] and recently in [14,35] it has been pointed out that without NNLO QCD corrections to EWP contribution the results for ε /ε are renormalization-scheme dependent and exhibit significant non-physical dependences on the scale µ t at which the top-quark mass m t (µ t ) is evaluated as well as on the matching scale µ W .…”
