Oral Presentation

This talk will present the latest phenomenological and simulated experimental prospective studies on the new physics opportunities at DarkSHINE Experiment by exploring the physics sensitivity of searching for dark fermions/sterile neutrinos and utilizing the positron beam mode to search for Dark Photon invisible decay signals in comparison with electron beam mode sensitivities.

Oral Presentation

arXiv:2602.23991 (Accetped by PRL)
We presents a combination of searches for Higgs boson pair (HH) production performed by the ATLAS and CMS Collaborations using proton-proton collision data sets recorded at √s = 13 TeV during the Large Hadron Collider Run 2, corresponding to integrated luminosities ranging between 126 and 140 $fb^{−1}$. The upper limit at the 95% confidence level on the...

17. Measurement of the Higgs boson decay to a low-mass dilepton system and a photon in $pp$ collisions at $\sqrt{s}$ = 13 and 13.6 TeV with the ATLAS detector

arxiv:2608.03369 (submitted to JHEP)
A measurement of the $H\rightarrow \gamma^{*}\gamma$ process in the $\ell\ell\gamma$ final state is performed using proton--proton collision data recorded with the ATLAS detector at $\sqrt{s}$ = 13.6 TeV during the years 2022--2024, corresponding to an integrated luminosity of 164 fb$^{-1}$. A simultaneous unbinned maximum-likelihood fit to the...

9. Correlative study of flavor anomalies and dark matter in the light of scalar leptoquark

DHIREN PANDA (University of Hyderabad)

Oral Presentation

We explore $U(1)_{L_e-L_\mu}$ gauge extension of the Standard Model with particle content enlarged by three neutral fermions, of which the lightest one contributes to dark matter content of the Universe. The scalar sector is enriched with a $\tilde{R}_2$ scalar leptoquark doublet to investigate flavor anomalies in $B$-meson sector and a scalar singlet to spontaneously break the new $U(1)$. We...
