Investigating the B-meson production based on the color dipole transverse momentum representation in pp collisions at the LHC

European Physical Journal C: Particles and Fields
In this work the B-mesons differential cross sections in pp collisions are evaluated considering the color dipole formalism in transverse momentum representation along with the unintegrated gluon distributions (UGDs). Analytical parametrizations for UGDs

Higgs decay to fermion pairs at NLO in SMEFT

Journal of High Energy Physics, 2020
The calculation of next-to-leading order (NLO) perturbative corrections at fixed operator dimension in Standard Model Effective Field Theory (SMEFT) has been a topic of much recent interest.

Holography and phenomenology [PDF]

Journal of High Energy Physics, 2001
We examine various aspects of the conjectured duality between warped AdS$_5$ geometries with boundary branes and strongly coupled (broken) conformal field theories coupled to dynamical gravity. We also examine compactifications with 5-d gauge fields, in which case the holographic dual is a broken CFT weakly coupled to dynamical gauge fields in addition

Phenomenology of Neutrino Oscillations [PDF]

, 2002
We review the status of several phenomenological topics of current interest in neutrino oscillations: (i) Solar neutrino oscillations after the first Sudbury Neutrino Observatory measurements, including both model-independent and model-dependent results;

Buried Treasure? Overlooked and Newly Discovered Evolutionary Contributions to Human Brain Diseases

Annals of Neurology, EarlyView.
Recapitulative schema of different exploratory levels of the evolutionary impact on human neurological diseases. Clinical neuroscience focuses on the mechanisms of brain function, but this approach falls short of insights into how the central nervous system (CNS) evolved, both in health and disease.

Simplified models of dark matter with a long-lived co-annihilation partner

Journal of High Energy Physics, 2017
We introduce a new set of simplified models to address the effects of 3-point interactions between the dark matter particle, its dark co-annihilation partner, and the Standard Model degree of freedom, which we take to be the tau lepton. The contributions

Dispersion of First Sound in a Weakly Interacting Ultracold Fermi Liquid

Annalen der Physik, EarlyView.
 The weak‐interaction, low‐temperature region of the phase diagram of a Fermi gas the so‐called Fermi liquid regime, which has been somewhat overlooked in ultracold gases‐is investigated. Precise and measurable predictions are presented for the viscosity and dispersion of first sound to leading order in the scattering length.

Adversarially-trained autoencoders for robust unsupervised new physics searches

Journal of High Energy Physics, 2019
Machine learning techniques in particle physics are most powerful when they are trained directly on data, to avoid sensitivity to theoretical uncertainties or an underlying bias on the expected signal.

Neutron Electric Dipole Moment from Beyond the Standard Model

, 2012
We discuss the phenomenology of neutron Electric Dipole Moment from the Standard Model and beyond, and identify the matrix elements most necessary to connect the current and forthcoming experiments with phenomenology.

Supercurrents and Tunneling in Massive Many‐Vortex Necklaces and Star‐Lattices

Annalen der Physik, EarlyView.
It is numerically shown how massive many‐vortex systems, in a mixture of Bose–Einstein condensates, can host the bosonic tunneling of the infilling component in an almost‐periodic way when the vortices are organized in necklaces or star‐lattices. The purpose is to explore the conditions for the onset of Josephson supercurrents in rotating many‐vortex ...
