We investigate the potential for detecting pion-like dark matter within the framework of a Strongly Interacting Massive Particle (SIMP) model using the MoEDAL Apparatus for Penetra…
Minicharged Particle Sensitivity of the MAPP Outrigger Detector
Matti Kalliokoski, Vasiliki A. Mitsou, Marc de Montigny +5
We present a detailed study of the projected background-free sensitivity of the MAPP Outrigger Detector (OD) to minicharged particles (mCPs) at the High-Luminosity Large Hadron Col…
Dihadron Angular Correlations in the Collision
Wan-Li Ju, Zhe-Yan Shu, Tong-Zhi Yang +2
The precision of fixed-order calculations on the dihadron production in electron-positron annihilation is paramount for probing QCD factorization and constraining non-perturbative…
Dark Matter Candidates and Searches
Nassim Bozorgnia, Joseph Bramante, James M. Cline +7
Astrophysical observations suggest that most of the matter in the cosmos consists of a new form that has not been observed on Earth. The nature and origin of this mysterious dark m…
The and spectra in top-antitop hadroproduction at NNLL+NNLO: the interplay of soft-collinear resummation and Coulomb singularities
Wan-Li Ju, Marek Schoenherr
In this paper, we present the resummation-improved differential transverse momentum and azimuthal decorrelation cross sections, and $dσ_{t\bar{t}}/d…
Cosmic Ray Muons in Laboratories Deep Underground
William Woodley, Anatoli Fedynitch, Marie-Cécile Piro
We provide comprehensive calculations of total muon fluxes, energy and angular spectra, and mean muon energies in deep underground laboratories - under flat overburdens and mountai…
Semileptonic Decay to the Meson with Lepton Pairs in Heavy Quark Effective Theory Factorization upto
Saadi Ishaq, Sajawal Zafar, Abdur Rehman +1
Motivated by the study of heavy-light meson production within the framework of heavy quark effective theory (HQET) factorization, we extend the factorization formalism for a rather…
Model for bubble nucleation efficiency of low-energy nuclear recoils in bubble chambers for dark matter detection
Xiang Li, Marie-Cécile Piro
Bubble chambers are promising technologies for detecting low-energy nuclear recoils from the elastic scattering of dark matter particle candidates. Bubble nucleation occurs when th…

Vasiliki A. Mitsou, Marc de Montigny, Abhinab Mukhopadhyay +4
MoEDAL's Apparatus for Penetrating Particles (MAPP) Experiment is designed to expand the search for new physics at the LHC, significantly extending the physics program of the basel…
Oscillating Fields, Emergent Gravity and Particle Traps
Alexander A. Penin, Aneca Su
We study the large-scale dynamics of charged particles in a rapidly oscillating field and formulate its classical and quantum effective theory description. The high-order perturbat…
The Q_{1,2}-Q_7 interference contributions to b -> s gamma at O(alpha_s^2) for the physical value of m_c
M. Czaja, M. Czakon, T. Huber +5
The B -> X_s gamma branching ratio is currently measured with around 5% accuracy. Further improvement is expected from Belle II. To match such a precision on the theoretical side,…
DAEMONFLUX: DAta-drivEn MuOn-calibrated atmospheric Neutrino Flux
Juan Pablo Yañez, Anatoli Fedynitch
In this paper, we present a refined calculation of the atmospheric neutrino flux spanning from GeV to PeV energies. Our method, Daemonflux, utilizes data-driven inputs and incorpor…
Positronium hydride decay into proton, electron, and one or zero photons
