We report results of a study doubly charmed baryons and strange baryons. The analysis is performed using $980\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected with the Belle detector at KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. search for ${\mathrm{\ensuremath{\Xi}}}_{cc}^{+(+)}$ ${\mathrm{\ensuremath{\Lambda}}}_{c}^{+}{K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}({\ensuremath{\pi}}^{+})$...
Session-based recommendation (SBR) aims to predict the following item a user will interact with during an ongoing session. Most existing SBR models focus on designing sophisticated neural-based encoders learn session representation, capturing relationship among items. However, they tend last item, neglecting diverse intents that may exist within This limitation leads significant performance drops, especially for longer sessions. To address this issue, we propose novel model, called...
We report a measurement of ${D}^{0}\text{\ensuremath{-}}{\overline{D}}^{0}$ mixing parameters and search for indirect $CP$ violation through time-dependent amplitude analysis ${D}^{0}\ensuremath{\rightarrow}{K}_{S}^{0}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ decays. The results are based on $921\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data accumulated with the Belle detector at KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. Assuming conservation, we...
We present the first measurements of absolute branching fractions $\Xi_c^+$ decays into $\Xi^- \pi^+ \pi^+$ and $p K^- final states. Our analysis is based on a data set $(772\pm 11)\times 10^{6}$ $B\bar{B}$ pairs collected at $\Upsilon(4S)$ resonance with Belle detector KEKB $e^+e^-$ collider. measure fraction $\bar{B}^{0} \to \bar{\Lambda}_{c}^{-} \Xi_{c}^{+}$ recoiling against $\bar{\Lambda}_c^-$ in $\bar{B}^0$ resulting ${\cal B}(\bar{B}^{0} \Xi_{c}^{+}) = [1.16 \pm 0.42(\rm stat.)...
We search for $CP$ violation in the charged charm meson decay ${D}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{0}$, based on a data sample corresponding to an integrated luminosity of $921\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected by Belle experiment at KEKB ${e}^{+}{e}^{\ensuremath{-}}$ asymmetric-energy collider. The measured $CP$-violating asymmetry is...
We report measurements of $B$ to pseudoscalar-pseudoscalar decays with at least one $\ensuremath{\eta}$ meson in the final state using $140\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data collected by Belle detector KEKB ${e}^{+}{e}^{\ensuremath{-}}$ collider. observe decay ${B}^{+}\ensuremath{\rightarrow}\ensuremath{\eta}{\ensuremath{\pi}}^{+}$ and find evidence ${B}^{+}\ensuremath{\rightarrow}\ensuremath{\eta}{K}^{+}$; measured branching fractions are...
We present a new measurement of CP-violation parameters in B(0)-->K(0)(S)pi(0)gamma decay based on sample 275 x 10(6) BB pairs collected at the Gamma(4S) resonance with Belle detector KEKB energy-asymmetric e(+)e(-) collider. One B mesons is fully reconstructed decay. The flavor accompanying meson identified from its products. are obtained asymmetry distribution proper time intervals between two decays. obtain SK(0)(S)(pi(0)gamma) = -0.58(+0.46)(-0.38)(stat) +/- 0.11(syst) and...
We report a measurement of the cross section for ${K}_{S}^{0}$ pair production in single-tag two-photon collisions, ${\ensuremath{\gamma}}^{*}\ensuremath{\gamma}\ensuremath{\rightarrow}{K}_{S}^{0}{K}_{S}^{0}$, ${Q}^{2}$ up to $30\text{ }\text{ }{\mathrm{GeV}}^{2}$, where is negative invariant mass squared tagged photon.

The first search for $Z_{c}$ pair production in $\Upsilon(1S)$ and $\Upsilon(2S)$ decays $e^{+}e^{-}$ annihilation at $\sqrt{s}$ = 10.52, 10.58, 10.867 GeV is conducted using data collected with the Belle detector KEKB asymmetric energy electron-positron collider. No significant signals are observed any of studied modes, 90\% credibility level upper limits on their product branching fractions (${\cal B}(\Upsilon(1S,2S)\to Z^{+}_{c}Z^{(\prime) -}_{c})\times{\cal B}(Z^{+}_{c}\to\pi^{+}+c\bar...
Linear autoencoder models learn an item-to-item weight matrix via convex optimization with L2 regularization and zero-diagonal constraints. Despite their simplicity, they have shown remarkable performance compared to sophisticated non-linear models. This paper aims theoretically understand the properties of two terms in linear autoencoders. Through lens singular value decomposition (SVD) principal component analysis (PCA), it is revealed that enhances impact high-ranked PCs. Meanwhile,...
Query reformulation is a key mechanism to alleviate the linguistic chasm of query in ad-hoc retrieval. Among various solutions, reduction effectively removes extraneous terms and specifies concise user intent from long queries. However, it challenging capture hidden diverse intent. This paper proposes Contextualized Reduction (ConQueR) using pre-trained language model (PLM). Specifically, reduces verbose queries with two different views: core term extraction sub-query selection. One extracts...
