We investigate a potential of measuring properties of a heavy resonance X, exploiting jet substructure techniques. Motivated by heavy higgs boson searches, we focus on the decays of X into a pair of (massive) electroweak gauge bosons. [...]

First Results from Axion Haloscope at CAPP around 10.7 $\mu$eV
/ CAPP Collaboration
The Center for Axion and Precision Physics research at the Institute for Basic Science is searching for axion dark matter using ultra-low temperature microwave resonators. We report the exclusion of the axion mass range 10.7126$-$10.7186 $\mu$eV with near Kim-Shifman-Vainshtein-Zakharov (KSVZ) coupling sensitivity and the range 10.16$-$11.37 $\mu$eV with about 9 times larger coupling at 90$\%$ confidence level.

OPTIMASS: A Package for the Minimization of Kinematic Mass Functions with Constraints
/ Cho, Won Sang (Florida U. ; IBS, Daejeon, CTPU) ; Gainer, James S. (Florida U.) ; Kim, Doojin (Florida U.) ; Lim, Sung Hak (IBS, Daejeon, CTPU ; KAIST, Taejon) ; Matchev, Konstantin T. (Florida U.) ; Moortgat, Filip (CERN) ; Pape, Luc (CERN) ; Park, Myeonghun (APCTP, Pohang ; POSTECH, Pohang ; Tokyo U., IPMU)
Reconstructed mass variables, such as $M_2$, $M_{2C}$, $M_T^\star$, and $M_{T2}^W$, play an essential role in searches for new physics at hadron colliders. The calculation of these variables generally involves constrained minimization in a large parameter space, which is numerically challenging. [...]

Improving the sensitivity of stop searches with on-shell constrained invariant mass variables
/ Cho, Won Sang (Florida U. ; IBS, Daejeon, CTPU) ; Gainer, James S. (Florida U.) ; Kim, Doojin (Florida U.) ; Matchev, Konstantin T. (Florida U.) ; Moortgat, Filip (CERN) ; Pape, Luc (CERN) ; Park, Myeonghun (Tokyo U., IPMU ; APCTP, Pohang ; POSTECH)
The search for light stops is of paramount importance, both in general as a promising path to the discovery of beyond the standard model physics and more specifically as a way of evaluating the success of the naturalness paradigm. While the LHC experiments have ruled out much of the relevant parameter space, there are "stop gaps", i.e., values of sparticle masses for which existing LHC analyses have relatively little sensitivity to light stops.

Effective Theory Approach for Axion Wormholes
/ Cheong, Dhong Yeon (IPAP, Seoul ; Yonsei U. ; CERN) ; Park, Seong Chan (IPAP, Seoul ; Yonsei U. ; Korea Inst. Advanced Study, Seoul) ; Shin, Chang Sub (Chungnam Natl. U. ; IBS, Daejeon, CTPU ; Korea Inst. Advanced Study, Seoul)
We employ the effective field theory approach to analyze the characteristics of Euclidean wormholes within axion theories. Using this approach, we obtain non-perturbative instantons in various complex scalar models with and without a non-minimal coupling to gravity, as well as models featuring the $R^2$ term for a range of coupling values.

The detection of cosmic antideuterons ($\overline{\rm D}$) at kinetic energies below a few GeV/n could provide a smoking gun signature for dark matter (DM). [...]

Quasi-Jacobi Forms, Elliptic Genera and Strings in Four Dimensions
/ Lee, Seung-Joo (IBS, Daejeon, CTPU) ; Lerche, Wolfgang (CERN) ; Lockhart, Guglielmo (CERN) ; Weigand, Timo (U. Mainz, PRISMA ; Mainz U., Inst. Phys.)
We investigate the interplay between the enumerative geometry of Calabi-Yau fourfolds with fluxes and the modularity of elliptic genera in four-dimensional string theories. We argue that certain contributions to the elliptic genus are given by derivatives of modular or quasi-modular forms, which encode BPS invariants of Calabi-Yau or non-Calabi-Yau threefolds that are embedded in the given fourfold.

/ Battesti, Rémy (LNCMI, Toulouse) ; Beard, Jerome (LNCMI, Toulouse) ; Böser, Sebastian (Mainz U., Inst. Phys.) ; Bruyant, Nicolas (LNCMI, Toulouse) ; Budker, Dmitry (Mainz U., Inst. Phys. ; Helmholtz Inst., Mainz ; UC, Berkeley ; LBL, Berkeley) ; Crooker, Scott A. (Los Alamos) ; Daw, Edward J. (Sheffield U.) ; Flambaum, Victor V. (Mainz U., Inst. Phys. ; Helmholtz Inst., Mainz ; New South Wales U.) ; Inada, Toshiaki (Tokyo U., ICEPP) ; Irastorza, Igor G. (Zaragoza U.) et al.
Various fundamental-physics experiments such as measurement of the birefringence of the vacuum, searches for ultralight dark matter (e.g., axions), and precision spectroscopy of complex systems (including exotic atoms containing antimatter constituents) are enabled by high-field magnets. We give an overview of current and future experiments and discuss the state-of-the-art DC- and pulsed-magnet technologies and prospects for future developments..
