Theory Status - Puzzles in B Meson Decays and LFU?

SciPost Physics Proceedings, 2019
Currently B meson puzzles motivate many studies of New Physics due to the observed deviations from the Standard Model predictions. There are two B meson puzzles, RD(∗) and RK(∗).

Model Independent Bounds on Magnetic Moments of Majorana Neutrinos [PDF]

, 2006
We analyze the implications of neutrino masses for the magnitude of neutrino magnetic moments. By considering electroweak radiative corrections to the neutrino mass, we derive model-independent naturalness upper bounds on neutrino magnetic moments, $\mu_\

Cerebrospinal Fluid Liquid Biopsy Enables Targeted Therapy Without Tissue Diagnosis in Pediatric Low‐Grade Gliomas With BRAF V600E Mutation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT We present two pediatric cases of pediatric low‐grade gliomas (PLGG) with BRAF V600E mutations diagnosed and monitored using cerebrospinal fluid (CSF) liquid biopsy analyzed via digital droplet PCR (ddPCR), without tissue biopsy. Both patients were treated with dabrafenib and trametinib and monitored through clinical assessments, magnetic ...

Ten years older and no wiser

Condensed Matter Physics, 2005
In a moment of madness, I wrote a summary of my life for the volume of Molecular Physics that noted my sixtieth anniversary. Evidently, I must have caused the editors of this issue some problems because in revenge they have requested that I write ...

Student sensemaking about inconsistencies in a reform-based introductory physics lab

Physical Review Physics Education Research, 2022
There is growing interest in implementing reform-based lab courses in undergraduate physics that are student driven rather than instructor driven. In these courses, students develop and carry out experiments while simultaneously reasoning about their ...

Plans for a Neutron EDM Experiment at SNS [PDF]

, 2007
The electric dipole moment of the neutron, leptons, and atoms provide a unique window to Physics Beyond the Standard Model. We are currently developing a new neutron EDM experiment (the nEDM Experiment).

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

What could we learn about high energy particle physics from cosmological observations at largest spatial scales ?

EPJ Web of Conferences, 2017
The very well known example of cosmology testing particle physics is the number of relativistic particles (photons and three active neutrinos within the Standard Model) at primordial nucleosynthesis.

Optical Measurement of Photorecombination Time Delays

Ultrafast Science, 2023
Recollision physics and attosecond pulse generation meld the precision of optics with collision physics. As a follow-up to our previous work, we reveal a new direction for the study of electronic structure and multielectron dynamics by exploiting the ...

Sensitivity to new physics: a_e vs. a_mu

, 2008
At present it is generally believed that ``new physics'' effects contribute to leptonic anomalous magnetic moment, a_l, via quantum loops only and they are proportional to the squared lepton mass, (m_l)^2.
