The 750 GeV diphoton excess in particle physics was an anomaly in data collected at the Large Hadron Collider (LHC) in 2015, which could have been an indication of a new particle or resonance. [ 8 ] [ 9 ] The anomaly was absent in data collected in 2016, suggesting that the diphoton excess was a statistical fluctuation.
In quantum physics an anomaly or quantum anomaly is the failure of a symmetry of a theory's classical action to be a symmetry of any regularization of the full quantum theory. [1] [2] In classical physics, a classical anomaly is the failure of a symmetry to be restored in the limit in which the symmetry-breaking parameter goes to zero.
Anomaly, a rift in the space-time continuum in the television series Futurama; Anomaly, any shortcut to hyperspace travel in Robert Heinlein's novels of the 1950s, today called wormholes "Anomaly" (Star Trek: Enterprise), a 2003 episode of Star Trek: Enterprise; The Anomaly, a 2014 film; Anomaly (comics), a villain in DC Comics
A congenital malformation is a physical anomaly that is deleterious, i.e. a structural defect perceived as a problem. A typical combination of malformations affecting more than one body part is referred to as a malformation syndrome. [citation needed] Some conditions are due to abnormal tissue development:
Anomalies in the usual 4 spacetime dimensions arise from triangle Feynman diagrams. In theoretical physics, a gravitational anomaly is an example of a gauge anomaly: it is an effect of quantum mechanics — usually a one-loop diagram—that invalidates the general covariance of a theory of general relativity combined with some other fields.
Minor physical anomalies (MPAs) are relatively minor (typically painless and, in themselves, harmless) congenital physical abnormalities consisting of features such as low-set ears, single transverse palmar crease, telecanthus, micrognathism, macrocephaly, hypotonia and furrowed tongue.
About 3% of newborns have a "major physical anomaly", meaning a physical anomaly that has cosmetic or functional significance. [24] Congenital disorders are responsible for 20% of infant deaths. [25] The most common congenital diseases are heart defects, Down syndrome, and neural tube defects. Trisomy 21 is the most common type of Down Syndrome.
A vascular anomaly is any of a range of lesions from a simple birthmark to a large tumor that may be disfiguring. They are caused by a disorder of the vascular system. [1] A vascular anomaly is a localized defect in blood vessels or lymph vessels. These defects are characterized by an increased number of vessels, and vessels that are both ...
