OLD PICTURE. “Several authors assumed that at some low momentum scale the sea quarks and gluons vanish, and at high momentum scales they are all generated by gluon radiation and then gluon splitting. These assumptions were used to describe successfully the existing data in the late 1970s.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

NEW CARTOON. “In the early 1990s the New Muon Collaboration (NMC) reported measurements of the deep inelastic structure functions (F2) of hydrogen (H) and deuterium (D).” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

PARTICLE MENAGERIE. “The Drell–Yan process in hadron–hadron collisions is a reaction in which a quark and an antiquark annihilate into a virtual photon, and that virtual photon decays into a lepton–antilepton pair.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

QUARK-ANTIQUARK COLLISIONS. “One can isolate the antiquark distributions from the Drell–Yan cross-section by making use of this property.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

THE PROBLEM. “There are various mechanisms that may account for the antiquark flavour asymmetry of the proton.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

ONE EXPLANATION. “Pauli blocking may lead to a flavour asymmetry as the extra u valence quark Pauli blocks some matter-antimatter pairs from forming.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

POWERFUL IMAGES. “It has long been claimed that imagery can have unique, if not profound, effects in physiological activity and health. With few exceptions, most of these observations have been ignored by mainstream medicine and psychology.” (Chapter 2). https://lnkd.in/dfMNaXbV View in LinkedIn

Possibly the most carefully written cookbook I have ever seen, exquisitely describing the endless world of fermented food. A masterpiece of literature and imagination. View in LinkedIn

HUGE PROMISE. “These results affect the reach of a p–p collider, such as the Large Hadron Collider, for new physics.” https://www.nature.com/articles/s41586-021-03282-z View in LinkedIn

ANTIGRAVITY. “We review the main arguments against antigravity, a different acceleration of antimatter relative to matter in a gravitational field.” https://lnkd.in/daA2SgMy View in LinkedIn
