Lung adenocarcinoma is the most common type of lung cancer. Known risk variants explain only a small fraction of lung adenocarcinoma heritability. Here, we conducted a two-stage genome-wide association study of lung adenocarcinoma of East Asian ancestry (21,658 cases and 150,676 controls; 54.5% never-smokers) and identified 12 novel susceptibility variants, bringing the total number to 28 at 25 independent loci. Transcriptome-wide association analyses together with colocalization studies using a Taiwanese lung expression quantitative trait loci dataset (n = 115) identified novel candidate genes, including FADS1 at 11q12 and ELF5 at 11p13. In a multi-ancestry meta-analysis of East Asian and European studies, four loci were identified at 2p11, 4q32, 16q23, and 18q12. At the same time, most of our findings in East Asian populations showed no evidence of association in European populations. In our studies drawn from East Asian populations, a polygenic risk score based on the 25 loci had a stronger association in never-smokers vs. individuals with a history of smoking (P = 0.0058). These findings provide new insights into the etiology of lung adenocarcinoma in individuals from East Asian populations, which could be important in developing translational applications.

We report searches for B0→invisible and B0→invisible+γ decays, where the energy of the photon is required to be larger than 0.5 GeV. These results are obtained from a 711 fb−1 data sample that contains 772×106BB¯ pairs and was collected near the ϒ(4S) resonance with the Belle detector at the KEKB e+e− collider. We observe no significant signal for either decay and set upper limits on their branching fractions at 90% confidence level of B(B0→invisible)<7.8×10−5 and B(B0→invisible+γ)<1.6×10−5.

We report new measurements of the production cross sections of pairs of charged pions and kaons as a function of their fractional energies using various fractional-energy definitions. Two different fractional-energy definitions were used and compared to the conventional fractional-energy definition reported previously. The new variables aim at either identifying dihadron cross sections in terms of single-hadron fragmentation functions, or to provide a means of characterizing the transverse momentum created in the fragmentation process. The results were obtained applying the updated initial-state radiation correction used in other recent Belle publications on light-hadron production cross sections. In addition, production cross sections of single charged pions, kaons, and protons were also updated using this initial-state radiation correction. The cross sections are obtained from a 558 fb−1 data sample collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider.

We report the results of a first search for a doubly charged DDK bound state, denoted the R++, in ϒ(1S) and ϒ(2S) inclusive decays and via direct production in e+e− collisions at s=10.520, 10.580, and 10.867 GeV. The search uses data accumulated with the Belle detector at the KEKB asymmetric-energy e+e− collider. No significant signals are observed in the D+Ds*+ invariant-mass spectra of all studied modes. The 90% credibility level upper limits on their product branching fractions in ϒ(1S) and ϒ(2S) inclusive decays (B(ϒ(1S, 2S)→R+++anything)×B(R++→D+Ds*+)), the product values of Born cross section and branching fraction in e+e− collisions (σ(e+e−→R+++anything)×B(R++→D+Ds*+)) at s=10.520, 10.580, and 10.867 GeV under different assumptions of R++ masses varying from 4.13 to 4.17 GeV/c2 and widths varying from 0 to 5 MeV are obtained.

Using 980 fb−1 of data collected with the Belle detector operating at the KEKB asymmetric-energy e+e− collider, we report a study of the electromagnetic decays of excited charmed baryons Ξc(2790) and Ξc(2815). A clear signal (8.6 standard deviations) is observed for Ξc(2815)0→Ξc0γ, and we measure: B[Ξc(2815)0 → Ξc0γ]B[Ξc(2815)0 → Ξc(2645)+π− → Ξc0π+π−]=0.41±0.05±0.03. We also present evidence (3.8 standard deviations) for the similar decay of the Ξc(2790)0 and measure: B[Ξc(2790)0 → Ξc0γ]B[Ξc(2790)0 → Ξc′+π− → Ξc+γπ−]=0.13±0.03±0.02. The first quoted uncertainties are statistical and the second systematic. We find no hint of the analogous decays of the Ξc(2815)+ and Ξc(2790)+ baryons and set upper limits at the 90% confidence level of: B[Ξc(2815)+ → Ξc+γ]B[Ξc(2815)+ → Ξc(2645)0π+ → Ξc+π−π+]<0.09, and B[Ξc(2790)+ → Ξc+γ]B[Ξc(2790)+ → Ξc′0π+ → Ξc0γπ+]<0.06. Approximate values of the partial widths of the decays are extracted, which can be used to discriminate between models of the underlying quark structure of these excited states.

We report a search for the charmless baryonic decay B0→pp¯π0 with a data sample corresponding to an integrated luminosity of 711 fb−1 containing (772±10)×106 BB¯ pairs. The data were collected by the Belle experiment running on the ϒ(4S) resonance at the KEKB e+e− collider. We measure a branching fraction B(B0→pp¯π0)=(5.0±1.8±0.6)×10−7, where the first uncertainty is statistical and the second is systematic. The signal has a significance of 3.1 standard deviations and constitutes the first evidence for this decay mode. We also search for the intermediate two-body decays B0→Δ+p¯ and B0→Δ¯−p, and set an upper limit on the branching fraction, B(B0→Δ+p¯)+B(B0→Δ¯−p)<1.6×10−6 at 90% confidence level.

The originally published version of this Article contained an error in Figure 2. In panel g, the image of brown adipose tissue from SCD-fed Tph1 GKO mice (top-right) was inadvertently replaced with the equivalent image of SCD-fed WT mice (top-left) during assembly of the figure. This error has now corrected in both the PDF and HTML versions of the Article.

Using data collected in the Belle experiment at the KEKB asymmetric-energy e+e− collider we search for transitions ϒ(4S)→ηb(1S)ω, ϒ(5S)→ηb(1S)ω and ϒ(5S)→ηb(2S)ω. No significant signals are observed and we set 90% confidence level upper limits on the corresponding visible cross sections: 0.2 pb, 0.4 pb and 1.9 pb, respectively.

Using a data sample of 772×106 BB¯ pairs collected on the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e− collider, we report the observation of B0→pp¯π+π− and the first observation of B+→pp¯π+π0. We measure a decay branching fraction of (0.83±0.17±0.17)×10−6 in B0→pp¯π+π− for Mπ+π−<1.22 GeV/c2 with a significance of 5.5 standard deviations. The contribution from B0→pp¯K0 is excluded. We measure a decay branching fraction of (4.58±1.17±0.67)×10−6 for B+→pp¯π+π0 with Mπ+π0<1.3 GeV/c2 with a significance of 5.4 standard deviations. We study the difference of the Mpp¯ distributions in B0→pp¯π+π− and B+→pp¯π+π0.

We present the results of the first Dalitz plot analysis of the decay D0→K−π+η. The analysis is performed on a data set corresponding to an integrated luminosity of 953 fb−1 collected by the Belle detector at the asymmetric-energy e+e− KEKB collider. The Dalitz plot is well described by a combination of the six resonant decay channels K¯*(892)0η, K−a0(980)+, K−a2(1320)+, K¯*(1410)0η, K*(1680)−π+ and K2*(1980)−π+, together with Kπ and Kη S-wave components. The decays K*(1680)−→K−η and K2*(1980)−→K−η are observed for the first time. We measure ratio of the branching fractions, B(D0→K−π+η)B(D0→K−π+)=0.500±0.002(stat)±0.020(syst)±0.003(BPDG). Using the Dalitz fit result, the ratio B(K*(1680)→Kη)B(K*(1680)→Kπ) is measured to be 0.11±0.02(stat)−0.04+0.06(syst)±0.04(BPDG); this is much lower than the theoretical expectations (≈1) made under the assumption that K*(1680) is a pure 13D1 state. The product branching fraction B(D0→[K2*(1980)−→K−η]π+)=(2.2−1.9+1.7)×10−4 is determined. In addition, the πη′ contribution to the a0(980)± resonance shape is confirmed with 10.1σ statistical significance using the three-channel Flatté model. We also measure B(D0→K¯*(892)0η)=(1.41−0.12+0.13)%. This is consistent with, and more precise than, the current world average (1.02±0.30)%, deviates with a significance of more than 3σ from the theoretical predictions of (0.51–0.92)%.
